Introduction and Overview The XXI International Symposium on Lepton and Photon Interactions at High Energies (Lepton Photon 2003) was held 11 – 16 August 2003 at the Fermi National Accelerator Laboratory in Batavia, Illinois, USA. The Lepton Photon Symposium is the major international particle physics conference, held in odd-numbered years, alternating with the International Conference on High Energy Physics (ICHEP). Both the ICHEP conferences and the Lepton Photon symposia are sponsored by the International Union of Pure and Applied Physics (IUPAP). The Lepton Photon Symposium is traditionally by invitation only and consists entirely of plenary presentations. It has become a symposium devoted to the full breadth of particle physics rather than being specifically limited to physics of leptons and photons. Lepton Photon 2003 was organized by a Local Organizing Committee at Fermilab whose membership is shown in Appendix A. The International Advisory Committee is shown in Appendix B. As Lepton Photon Symposia have only plenary sessions, they historically have not had an additional Scientific Program Committee. The Lepton Photon 2003 scientific program was organized by a sub-committee of the Local Organizing Committee chaired by R. Keith Ellis, with advice from the International Advisory Committee. This report discusses the invitation process, the program and associated activities and the finances of Lepton Photon 2003. Additional information about Lepton Photon 2003 may be found at the Symposium website at http://conferences.fnal.gov/lp2003/. Invitations and Participation The invitation process for Lepton Photon 2003 was complex. We will attempt to describe it here. Invitations to IUPAP-sponsored conferences in particle physics are handled by a set of country coordinators appointed by the Particles and Fields commission (C11) of IUPAP. We obtained the list of country coordinators from the web site of the ICHEP 2002 meeting, held in Amsterdam 24 – 31 July 2002. Three institutions (CERN, JINR and ICTP) historically receive their own quotas separate from the countries in which they are located. Most of the country coordinators responded to us, but there were some changes in a few countries. Eventually we received responses from all countries on the list except Portugal and Romania. It would be helpful to conference organizers if IUAPAP C-11 would annually update the country coordinator list and make sure that the coordinators were still willing and able to serve. Country coordinators were each given a quota for invitations. The quotas were set based on the quotas on the ICHEP 2002 web site, with some adjustments. We made it clear that any country that wanted more invitations should let us know. A few countries requested small increases in their quotas. Table 1 shows the initial quota for each country and the number of invitees that each country sent to us. Many countries requested significantly fewer invitations than their quotas. Many people were invited outside of the country coordinator process. These included speakers, members of the local organizing and international advisory committees, poster presenters, scientific secretaries and members of IUPAP C-11. When it was clear that space was still available, additional invitations were extended to those on the “alternate” list for the USA. Report on Lepton Photon 2003 Symposium Page 3

Finally, just before the conference began, attendance was opened to additional scientists at Fermilab. The total number of invitations issued by category is shown in Table 2.

The participation rate was lower than we had expected – less than 60% of invitees actually attended the Symposium. The participation rate for the USA was 63% while for the rest of the world it was only 51%. The reasons for this are not clear though we know that some invitees were not able to attend due to difficulty obtaining visas. In particular, participation by scientists from China was greatly reduced. We issued 15 invitations to Chinese physicists. Eleven of these 15 indicated interest in attending Lepton Photon 2003 but only one was able to obtain a visa in time for the meeting. Table 5 shows the number of women among speakers, session chairs, etc. We are unable to present the numbers of female and male participants as we did not collect gender information from participants.

We made several efforts to increase the participation of younger physicists in the Lepton Photon 2003 Symposium. These efforts were successful and included the following: • A poster session was added. It is described in more detail in the next section. Both providing an opportunity to display work and providing a reduced registration fee were important in attracting younger scientists. • The Scientific Program committee tried to choose some younger speakers for the plenary talks. Many people commented that overall, there were more young speakers than is typical for a large international particle physics conference. • We had 32 young physicists serve as Scientific Secretaries for a reduced registration fee. • A few more young people got reduced registration fees by serving as tour guides. • There was an evening meeting of the Young Particle Physicists (http://ypp.hep.net/). One of the attendees at this meeting summarized it during a plenary session about the future outlook for particle physics. Program and Activities

Scientific Program The scientific program consisted of a series of plenary presentations. The scientific program may be found at http://conferences.fnal.gov/lp2003/program/ and is also included as Appendix C. The distribution of speakers and session chairs by region is shown in Table 6.

We lost one speaker and one session chair each from China when they were unable to obtain visas in time to attend. The replacement speaker and replacement session chair were both from the USA. Two of the speakers in Table 6 were representing international organizations (ICFA and IUPAP C-11). As it happened, both were from the USA. We added two new activities to Lepton Photon 2003 that had not been part of previous Lepton Photon Symposia:

Informal Break-out Sessions Because the Lepton Photon symposium has no parallel sessions, there have traditionally been few opportunities for participants to interact with the speakers. Although there is always some time allowed for questions following each talk, this is typically a small amount of time that does not permit much discussion. We added breakout sessions to increase opportunities for more informal scientific interchange. We did not reduce the number of plenary talks, so it was a little bit difficult to fit these in. We had some during lunch time and also on the final Friday afternoon of the Symposium when the tours of Fermilab were available. In spite of scheduling them during lunch, these sessions proved to be very popular and were quite lively.

Poster Session One of our goals for the Lepton Photon 2003 Symposium was to increase the participation of younger physicists. As the Lepton Photon Symposium has a format that features only plenary talks, opportunities for graduate students and post-docs to present their work are more limited than at a conference with parallel sessions. To address this problem, we added a poster session to the 2003 Lepton Photon Symposium and invited younger scientists to submit abstracts. As an additional incentive, we reduced the registration fee substantially for the poster presenters. Response to this idea started out slow, perhaps because it was a new idea for Lepton Photon and also partly due to our inexperience in publicizing it. Eventually though, we received more abstracts than we could accommodate. We had a total of 66 posters. The maximum number was set mostly by space for installation in the Fermilab Atrium but partly by the number of people we could afford to offer the registration subsidy. The posters were displayed at the opening of the Symposium, including at the reception. Many of the posters may be viewed on the Lepton Photon web site at http://conferences.fnal.gov/lp2003/posters/physics/phy_posters.html.

Proceedings from the 2003 Lepton Photon Symposium were published both in book form and DVD-ROM. The DVD contains streaming video of all presentations, as well as the write- ups published in the book. The Proceedings were completed within seven months of the Report on Lepton Photon 2003 Symposium Page 8

Symposium thanks to outstanding work by editors Harry W. K. Cheung and Tracey S. Pratt. In addition, there were 301 papers contributed to Lepton Photon 2003, available through the Lepton Photon 2003 web site (http://conferences.fnal.gov/lp2003/contributedpapers/).

Additional Activities Lepton Photon 2003 included many additional activities, both scientific and social, and we summarize them here. • Day 1: On the first evening of the Symposium, we had a reception in the Fermilab Atrium. At this time, posters prepared by younger physicists were on display. The reception was followed by a meeting of the Young Particle Physicists (YPP). • Day 2: We provided a barbecue dinner and a free concert. • Day 3: This was a free day with no talks scheduled. Bus transportation to the city of Chicago was provided and the Symposium dinner was held at Navy Pier in Chicago. • Day 4: Local Organizing Committee member Joel Butler organized a special session on “The Computational Data Grid and the Future of Distributed Computing”, held in the evening. This featured presentations by experts from the international Grid community as well as presentations from three vendors. We also had posters and displays related to Grid computing. This special session served to heighten awareness of the current activities in Grid computing. The Data Grid computing model is of interest to many scientists outside of particle physics. The session was advertised to the local community (both particle physics and information technology) as well as to the general public. The session was attended by approximately 350 people. While we would not expect to see every Lepton Photon meeting include a session on this topic, the Grid session proved to be a nice example of a program on a related scientific topic that could be held in conjunction with the Symposium and attract participation from a wider community. • Day 5: Following the morning session, the afternoon featured a variety of activities, including tours of Fermilab, break-out discussions, and a screening of “The Ultimate Particle” with the filmmaker in attendance. We mounted our third poster display of the Symposium with particle physics laboratories providing posters from all over the world. In the evening, Fermilab Director Michael Witherell delivered a public lecture.

Outreach Activities The Lepton Photon 2003 Symposium included several public outreach activities. The Lepton Photon 2003 Local Organizing Committee included a member (Ben Kilminster) charged with developing outreach activities. Ben, together with Organizing Committee member Herman White, arranged to do some demonstrations for the public at the Field Museum of Science in Chicago. This activity took place on 13 August 2003, the “free” day traditionally scheduled halfway through Lepton Photon meetings. Approximately 400 people interacted with the demonstrations over a four hour time period. Ben, with help from the Young Particle Physicists, also put together summaries of particle physics activity for the general public (http://conferences.fnal.gov/lp2003/forthepublic/) linked to the Lepton Photon 2003 web page. The summaries were also put on CDs along with a Report on Lepton Photon 2003 Symposium Page 9

series of videos about particle physics from the Fermilab Visual Media Services archive. These were distributed at the Field Museum. Additional copies of the CDs were made available to the Fermilab Education Office and the Fermilab Office of Public Affairs. Fermilab public information officer Judy Jackson organized a full program for members of the press and laboratory public information officers (see http://conferences.fnal.gov/lp2003/forthepress/). There were press panels on B Physics, Neutrino Physics, The Data Grid, and Exotic Physics. There was also a press panel featuring directors of many of the world’s particle physics laboratories. A total of 19 public information officers and media representatives registered (at no cost) for the Symposium. As part of this program, a new web site for particle physics news (http://www.interactions.org/) was launched. Other outreach activities included the special session on the Data Grid already described (and open to the public), a public lecture by Fermilab Director Michael Witherell titled “Windows on the Universe: New Questions about Matter, Space and Time”, and a showing of the film “The Ultimate Particle” by French film-maker Michel Andrieu who was in attendance. Finances The registration fee for Lepton Photon 2003 was set at $400 (early) or $450 (late). This was similar to the fees charged for other large international particle physics conferences in recent years and was consistent with guidelines from IUPAP. Because Lepton Photon 2003 was held at Fermilab, a U.S. Department of Energy (DOE) laboratory, there were restrictions on how money could be spent. In particular, we were required to separate the costs related to social activities. The “allowable” part of the registration fee was set at $275 (early or late) and attendees from the US Department of Energy, or DOE labs were charged only this amount. Table 7 shows the “allowable” costs and funding and Table 8 shows the costs and funding for special events. Thanks to generous support from the US Department of Energy, the US National Science Foundation, Universities Research Association and IUPAP, we were able to offer financial support ranging from waiving of the registration fee to full travel costs for many Lepton Photon 2003 attendees. The first Lepton Photon 2003 Bulletin invited those interested to apply for support by submitting a CV, a brief letter of recommendation from a supervising professor or senior scientist and a brief letter from the candidate. A total of 51 people applied for financial support. In addition, a few more requested that the registration fee be either waived or reduced. We were able to satisfy the support requests from all persons from developing countries who applied. Table 9 shows the countries of participants who received full or partial travel support. It also shows countries of persons who applied for and were awarded support, but were then unable to attend. The awardee from China and one of the awardees from Russia told us that they were unable to attend due to visa difficulties. Conclusions Lepton Photon 2003 was a very successful meeting, including a series of excellent plenary presentations covering the breadth of particle physics. Proceedings in both book form and on DVD were published within seven months of the Symposium. The addition of a poster session served to increase the participation of younger scientists. Attendance (645 participants) was somewhat lower than we had been expecting. This may have been partly due to difficulties obtaining visas experienced by some participants.
