This report contains summaries of 584 approved current and recent experiments in elementary particle physics. A glance at the summaries in the body of the report will show tiie kind of information given. Experiments at the following laboratories are included:
Brookhaven (BNL) Novosibirsk CERN Paul Srlierrrr Institute (PSI) formerly SIN CESR Sac-lay DESY Serpukhov Fermilab (FNAL) SLAC Institute for Nuclear Studies. Tokyo (INS) SSCL Institute for Theoretical and Experimental TRIUMF Physics. Moscow (ITEP) Underground experiments KEK Underwater experiments Los Alamos (LAMPF)
We exclude experiments for which the data collection was finished before 1986. The rationale for thus including many rather old experiments is that many of them are still producing papers: note that a summary includes a list of journal papers resulting from the experiment. We also exclude experiments mostly of interest to nuclear physicists, dealing with nuclear levels or other nuclear-structure measurements. There are of course experiments at the fuzzy borderline between particle and nuclear physics, and we have tried to make sensible choices about what experiments to include here. Sources of information — Our first information about an experiment usually comes from the proposal for the experiment. Then we follow the progress of the experiment as best we can in laboratory reports such as "Experiments at CERN." Finally, a few months before an edition of this report is to appear, we send copies of the summaries of the experiments to the spokespersons for checking and updating. If a reply is received — as was the case for almost 80% of the experiments there is a "v " next to the spokesperson on the summary. Since current experiments are often in flux, we rely heavily on these replies to be up to date: no v by the spokesperson means the summary may be inaccurate or incomplete. (For a handful of experiments, we verified our information with a local member of the experiment, not the spokesperson, but for simplicity put a
1 Abbreviations — To keep the summaries brief, abbreviations are used to indicate journals, kinematic variables, accelerators, and detectors. The abbreviations are usually obvious but. are defined near the beginning of the report. The abbreviated forms are needed for searching the EXPERIMENTS database online. Acknowledgments — G. Harigel and M. Varela Diaz (CERN), A. Stevens (BNL), and J. Parker (Fermilab) kindly provided computer files wi h data on experiments from their respective institutions, and L. Addis (SLAC) helped with the SI-IRES database system. We also thank the hundreds of spokespersons w-ho took the time to reply to our inquiries. Comments and requests — We invite comments pointing out omissions, obscurities, out- of-date information, and errors. We also encourage spokespersons to send us proposals and letters of intent of their future experiments.

2 SEARCHING THE "EXPERIMENTS" COMPUTER DATABASE VIA QSPIRES SERVER
General information As mentioned in the Introduction, the summaries in this report and sum maries of many earlier experiments are contained in a computer database named EXPERIMENTS main tained at SLAC under the SPIRES database management system. Anyone with an account on the SLAC's SLACVM computer may access this database by typing SPIRES, and then SELECT EXPERIMENTS. If you have a SLACVM account but are unfamiliar with SPIRES, a Guide to VM SPIRESis available from the SLAC Library. Mail-Stop 82, SLAC. P.O. Box 4349. Stanford. CA 913(10. USA (phone: 415/926 2411). The SPIRES search procedure in the EXPERIMENTS database is thoroughly described in the previous (1989) edition of this report.
The EXPERIMENTS database is also available under different systems in Europe. The Rutherford Appleton Laboratory, and CERN. have EXPERIMENTS implemented under the HEPDATA system on their central IBM/VM and VAX/VMS computers. A guest VAX/VMS account which enables the access to HEPDATA is available on the INTERNET node 129.234.8.100 (which is also a DEC'NET host 19788. or DURPDG): username PDG. password HEPDATA. Contact M. Whalley. Dept. of Physics. Univ. »{ Durham, South Road, Durham DH1 3LE. United Kingdom, (MRW«UKACRL.BITNET) for more infor mation. In Russia, the EXPERIMENTS is available at IHEP. Serpukhov, and JINR. Dulma. This and other IHEP high energy physics databases are managed by the BDMS/4 system and maintained by the Serpukhov COMPAS group. IHEP databases are also ; vailable on the CERN's VXCERN computer. Con tact V.V. Ezhela, Inst, for High Energy Physics. 142284 Serpukhov, Moscow Region. Russia. (EZHELA'" M9.IHEP.SU) for more information.
This section describes searching in the EXPERIMENTS database via the remote server QSPIRES at SLA.CVM. You do not need to have a SLACVM computer account to use QSPIRES. The server can be reached through e-mail from almost every international computer network, and also interactively from many BITNET sites. QSPIRES searching is free, and the only requirement is that your computer node is registered with SLAC. For more information on the registration, please contact QSPMSLACVM.BITNET or [email protected] . Many SPIRES databases, including EXPERIMENTS, are accessible via QSPIRES. The QSPIRES search commands are similar to those used in a direct SPIRES search. All extensive Guide to QSPIRES is available from the SLAC Library (see the address above).
QSPIRES search commands In the following text the BOLDFACE UPPER CASE letters denote the minimum part of a command. Note, however, that SPIRES and QSPIRES are rase insensitive, and in an actual search you may use both lower and upper case characters and may enter either the minimum or full commands.
• Note that whenever a search value contains special characters. ')' . '>' , "<* . or '(' , the entire search value must be enclosed in double quotes.
The three most useful command verbs are SHOw. BROwse and FINd. You can formulate a variety of search commands by using these three verbs. Some examples are:
SHOw INDexes (Shows available search terms. Use these terms with BROt/we and FINci.) BROwse Author TRILLING [Displays values in the author-name index surrounding the stated value.) BROwse EXPeriment-num (Gii'es several random values of experiment code-names.) BROwse EXPeriment-num DESY (Displays values in the code-name index alphabetically surrounding the specified value. Useful if yon do not know the exact form or spelling of a search value.) FINd Author RUBBIA, C or FINd Author C RUBBIA (Finds experiments in which the stated author has participated.) FINd EXPeriment-num DESY-HERA-H1 (Finds the record corresponding to the specified value.)
3 FINd PAPER "PR D37 (1988) 1131" (Fiiids the experiment reported in the stated reference. Note that the reference has sjiaces but no commas between the elements.) FINd REaction "E+ E- - - > MU+ MU- X" (The "arrow" is composed of two minus sigjis and a ' great er-t.hmi' sign.) FINd Accelerator KEK-TRISTAN (Finds experiments using the stated accelerator.) FINd DEtector MARK-II (Finds experiments using the stated detector.) FINd Title CP PHASE DIFFERENCE (Finds experiments with the. words CP. PHASE, and DIFFERENCE in the title. The order of words in the search command is unimportant.) FINd AFfiliation RUTGERS U or FINd AFfiliation RUTGERS# (Finds experiments with the stated affiliation. '#' represents any remaining characters.) FINd Particle HIGGS (Finds experiments studying the specified particle.) The following search commands are also allowed: FINd Author PREfix PATTERS or FINd Author PATTERS# (Finds authors whose last names begin with the string PATTERS, e.g.. Patterson.) FINd EXPeriment-num PREfix SLAC-SLC FINd AFSliation PREfix NORTHWEST Compound searching is also possible: FINd Author PERROT AND EXPeriment-num PREfix SACLAY FINd AFfiliation BOLOGNA U AND NOT Accelerator CERN-SPS FINd Particle J/PSI OR "PSI(2S)" Search commands are not the only elements in a QSPIRES search request. Often a search command has to be supplemented with additional instructions. For example, '(IN EXPERIMENTS', foiiowing a search command, is required to direct QSPIRES to the EXPERIMENTS database rather than the default HEP database. Such additional instructions are discussed below. Interactive QSPIRES searching From many BITNET nodes QSPIRES may be reached interac tively. (Interactive communication is not possible from non-BITNET nodes!) A typical interactive search request contains one-line text beginning with the address of QSPIRES. The addre.ss is followed by a search command, and a field indicating the desired database and other instructions: TELL QSPIRES AT SLACVM
4 No database selection is needed with the OUTput command. If tlie search result contains too many records, try to formulate a compound search request with more criteria. An example of a possible interactive session follows: TELL QSPIRES AT SLACVM SHO IND (IN EXPERIMENTS RES (QSPIRES responds) TELL QSPIRES AT SLACVM BRO DE CRYSTAL (IN EXPERIMENTS RES (QSPIRES responds) TELL QSPIRES AT SLACVM FIN DE CRYSTAL-BALL fc AC PRE SLAC (IN EXPERIMENTS RES (QSPIRES responds) TELL QSPIRES AT SLACVM OUT (QSPIRES sends the result of the search)
E-mail QSPIRES searching People who cannot or do not want to use the intcrai live procedure, may reach QSPIRES through e-mail. Send your search commands to QSPIRES'<»SLACVM.BITNET. or [email protected] . Leave the subject line in the header of your letter empty, and send only one search command per letter, e.g., BRO PARTICLE XI (IN EXPERIMENTS RESULT or FIN TITLE LARGE DETECTOR (IN EXPERIMENTS RES QSPIRES will answer through e-mail, and if you are satisfied with the number of retrieved documents, react immediately by sending the command 'OUTput'. If the search result contains loo many records, try to reformulate your request by adding more criteria. QSPIRES waits about 30 to 40 minutes for your follow-up command (e.g.. "OUTput.'). If it takes more tl an 20 minutes for a message to reach QSPIRES from your node, you cannot rely on follow-up search requests, and you should merge the search and output commands in a single request. You can do that by replacing RESult' in the option field with the 'FILe' option. For example, send the command FIN TITLE LARGE DETECTOR AND DATE > 1984 (IN EXPERIMENTS FILE The intermediate step in which QSPIRES reports the number of records found will be bypassed, and the retrieved records are sent immediately. Warning: if you are using this method, be sure that your search request is as restrictive as possible, by using several search criteria. Otherwise, you might be sent a file with a large number of records, and such long files travel very slowly or may even be deleted by some gateways.
Searching Problems: There are several common reasons why a search may fail: (1) Any search value containing any of tke special characters ) > < ( must be enclosed in double quotes: see the examples above for PAPER, REACTION, and PARTICLE searches. (2) You may have used an incorrect form of the value for which you were searching, e.g.. an incorrect particle or experiment code-name. To find the correct form., use the BROWSE command for the index you are searching (see above), or look in the lists of names and abbreviations beginning on page 21. Note, in. particular, that in reaction and particle searches an antiparticle name is formed by following the coiirsponding particle name with BAR (thus the antiproton is written as PBAR): in title searches, particle names are somewhat variable in their spelling, and several forms may be used. (3) You may have forgotten to select the EXPERIMENTS database. Always append the selection '(IN EXPERIMENTS' to your QSPIRES search request. (4) To be able to search via QSPIRES, you must be a registered user. If you are not. please contact QSPI&SLACVM.BITNET or [email protected] . (5) Try using SEND' or 'BSEND' instead of 'TELL' in interactive QSPIRES commands. Be sure BITNET is licensed on your computer.
5 OTHER DATABASES ACCESSIBLE WITH QSPIRES
Other SLAC public databases are available via QSPIRES. Besides EXPERIMENTS, they are are HEP. PARTICLES, CONF. HEPNAMES. INST. DATAGUIDE. and REACTION. (Refer In tin- llcnrw of I'nrlirl, Proprrtits. Phys. Rev. D45. SI (June 1992) for details on databases at other iustitul ions.) Following is a list and brief description of these SLAC public databases:
(1) PARTICLES contains the Full Listings from this litritir of Pinticlt Propfrtitx. indexed by particle and particle property. (2) HEP is a guide to particle physics preprints, journal articles, reports, t heses. conference papers, etc.. indexed by standard bibliographic entities as well as by citations and topics. HEP is a joint project of the SLAC and DESY libraries and. as of Juno 1992, contained almost 250.1)00 records dating from late 1974. It is updated daily with nearly 20,000 new records added each year. (3) CONF lists past and future conferences of interest to particle physicists. (•4) HEPNAMES lists e-mail addresses of many people working in high-energy physics. As of June 1992. more than 20,000 e-mail addresses were available. Additions and corrections may lie sent to: HFPNAMES«!SLACVM.BITNET. (5) INST lists nearly 3.000 addresses (often witli phone and fax numbers) of high-energy physics related institutions. (C) DATAGUIDE, an adjunct to HEP. indexes papers containing experimental data by accelerator, detector. beam momentum, reactions, and particles studied. (Not current: see DOCUMENT under the Serpukhov databases below.) (7} REACTIONS gives numerical data [r.y., cross sections, polarizations, etc.) on reactions. (8) EXPERIMENTS is a guide to current and past particle physics experiments, indexed similarly to HEP and DATAGUIDE.

GAMMA, ELECTRON, AND MUON EXPERIMENT Accelerator SSC Detector GEM Comments Exploits with the GEM detector the physics opportunities opened up by the new collider. The detector has a large superconducting open-geometry solenoid, emphasizing the detection of photons, electrons and muons with high precision. Muons will be tracked with a combination of drift tubes (in barrel region) and cathode strip chambers {end caps). with resistive plate counters in the barrel region to trigger on muons and tag beam crossings. The chambers surround the calorimeters and fill a large (16 m diameter, 30 m long), 0.8 T superconducting solenoid. Inside the calorimeters is a compact central tracker. The collaboration consists of 600 physicists from 15 countries, and is likely to grow. The development of a Technical Design Report is in progress (April 92). For further details, please contact the spokespersons. Dr. Barry Barish. Cal Tech. and Dr. William Willis, Columbia University. SSCL-SDC (1989) Approved Jan 1991. SOLENOIDAL DETECTOR COLLABORATION SDC COLLABORATION Accelerator SSC Detector SDC Comments The major goal is to exploit the physics :>portuni- ties opened up by the SSC collider with its design lu ninosity of 10 cm- s and counter-rotating beams of 20 TeV protons. The study will include the search for Higgs boson(s) and higher mass gauge bosons, new spectroscopies such as supersymmetry. and searches for compositeness effects and new phenomena not necessarily suggested by present theories. The detector has a large cylindrical volume (1.7 m radius by 8 m length) concentric with the beam and surrounded by a superconducting -olenoid coil that produces a 2 T magnetic field- The volume i.~ filled with tracking detectors which measure momenta and directions of charged particles emitted over the angular interval between 10 and 170°. Outside of the solenoid and tracking volume there is an hermetic central calorimeter providing total energy measure ments for electrons, photons, and hadron jets. The calorimeter includes a shower detector that provides position information on electromagnetic showers. Two forward calorimeter!. ;xt-nd the coverage for calorimetry down to 0.5°, and up to 179.5C On the outside uf the central calorimeter there is an extensive system for identifying and triggering on muons. The collaboration con sists of over 700 physicists and engineers from 12 countries, and is likely to grow. On April 1. 1992, the collaboration submit ted the Technical Design Report, and hopes to initiate construc tion in early 1993.

The main component of a module is a highly sensitive phototube. The experiment studies muons generated in neutrino interactions, measures Muxes of muons generated in the atmosphere, searches for local sources of very high-energy particles, gives limit on the flux of heavy magnetic monopoles catalyzing proton decay, etc. Data already taken with single string variants. The completion of the detector is expected in 1993/94. Papers NP (Proc. Suppl.) B14 (1990) 51, NP (Proc. Suppl.) B19 (1991) 388, and SJNP 52 (1990) 54. UNDERWATER-DUMAND (198U) Started Nov 1987.
