Muon Bundles As a Sign of Strangelets from the Universe
Draft version October 19, 2018 Typeset using LATEX default style in AASTeX61 MUON BUNDLES AS A SIGN OF STRANGELETS FROM THE UNIVERSE P. Kankiewicz,1 M. Rybczynski,´ 1 Z. W lodarczyk,1 and G. Wilk2 1Institute of Physics, Jan Kochanowski University, 25-406 Kielce, Poland 2National Centre for Nuclear Research, Department of Fundamental Research, 00-681 Warsaw, Poland Submitted to ApJ ABSTRACT Recently the CERN ALICE experiment, in its dedicated cosmic ray run, observed muon bundles of very high multiplicities, thereby confirming similar findings from the LEP era at CERN (in the CosmoLEP project). Originally it was argued that they apparently stem from the primary cosmic rays with a heavy masses. We propose an alternative possibility arguing that muonic bundles of highest multiplicity are produced by strangelets, hypothetical stable lumps of strange quark matter infiltrating our Universe. We also address the possibility of additionally deducing their directionality which could be of astrophysical interest. Significant evidence for anisotropy of arrival directions of the observed high multiplicity muonic bundles is found. Estimated directionality suggests their possible extragalactic provenance. Keywords: astroparticle physics: cosmic rays: reference systems arXiv:1612.04749v2 [hep-ph] 17 Mar 2017 Corresponding author: M. Rybczy´nski [email protected], [email protected], [email protected], [email protected] 2 Kankiewicz et al. 1. INTRODUCTION Cosmic ray physics is our unique source of information on events in the energy range which will never be accessible in Earth-bound experiments Dar & De Rujula(2008); Letessier-Selvon & Stanev(2011). This is why one of the most important aspects of their investigation is the understanding of the primary cosmic ray (CR) flux and its composition. -
Trigger and Data Acquisition
Trigger and data acquisition N. Ellis CERN, Geneva, Switzerland Abstract The lectures address some of the issues of triggering and data acquisition in large high-energy physics experiments. Emphasis is placed on hadron-collider experiments that present a particularly challenging environment for event se- lection and data collection. However, the lectures also explain how T/DAQ systems have evolved over the years to meet new challenges. Some examples are given from early experience with LHC T/DAQ systems during the 2008 single-beam operations. 1 Introduction These lectures concentrate on experiments at high-energy particle colliders, especially the general- purpose experiments at the Large Hadron Collider (LHC) [1]. These experiments represent a very chal- lenging case that illustrates well the problems that have to be addressed in state-of-the-art high-energy physics (HEP) trigger and data-acquisition (T/DAQ) systems. This is also the area in which the author is working (on the trigger for the ATLAS experiment at LHC) and so is the example that he knows best. However, the lectures start with a more general discussion, building up to some examples from LEP [2] that had complementary challenges to those of the LHC. The LEP examples are a good reference point to see how HEP T/DAQ systems have evolved in the last few years. Students at this school come from various backgrounds — phenomenology, experimental data analysis in running experiments, and preparing for future experiments (including working on T/DAQ systems in some cases). These lectures try to strike a balance between making the presentation accessi- ble to all, and going into some details for those already familiar with T/DAQ systems. -
Neutrino Oscillations: T2k and Na61 Experiments, R&D
NEUTRINO OSCILLATIONS: T2K AND NA61 EXPERIMENTS, R&D TOWARDS A FUTURE NEUTRINO PROGRAM 1 Research Plan The field of neutrino physics is certainly one of the most active in particle physics today. It is by now well established that neutrinos have mass and that the three families mix. In the minimal Standard Model, neutrinos are massless; massive neutrinos require either a new ad- hoc conservation law or new phenomena beyond the present framework, with a possible link to the grand unification scale via the see-saw mechanism. A deep field of research is thus open, that could last several decades and culminate with the discovery of leptonic CP violation – a key ingredient in the understanding of the baryon- anti-baryon asymmetry of the universe. Because observation of CP violation in neutrino oscillations requires appearance experiments, accessible at accelerators only, an important investment in accelerator-based neutrino beams and experiments is called for. The CHIPP Roadmap considers neutrino physics as one of the three pillars of particle physics in Switzerland, and so does the 15 years research plan of the DPNC at University of Geneva1. The neutrino group at DPNC has been actively involved in this quest since the nomination of Prof. A. Blondel in early 2000, where participation in the HARP experiment at CERN led us to the K2K experiment in Japan, in which the first observation of neutrino oscillation with a neutrino beam was achieved. The group received an added boost with the nomination of Alessandro Bravar (MER) in 2006. The research program comprises a progression of on- going experiments and far-reaching R&D activity as described in the SNF reports of October 2007 and October 2008. -

The motivation expanded with a wider range of applications. The tradi- for bringing LHC computing under the Berkeley Open In- tional CERN accelerator physics simulation code SixTrack frastructure for Network Computing (BOINC) [1] is that enjoys continuing volunteers support, and thanks to vir- available computing resources at CERN and in the HEP tualisation a number of applications from the LHC ex- community are not sucient to cover the needs for nu- periment collaborations and particle theory groups have merical simulation capacity. Today, active BOINC projects joined the consolidated LHC@Home BOINC project. This together harness about 7.5 Petaops of computing power, paper addresses the challenges related to traditional and covering a wide range of physical application, and also virtualized applications in the BOINC environment, and particle physics communities can benet from these re- how volunteer computing has been integrated into the sources of donated simulation capacity. -
Measurements of Hadronic Cross Section for Precise Determination of Neutrino Beam Properties in T2K Oscillation Experiment
University of Warsaw Faculty of Physics Institute of Experimental Physics Measurements of Hadronic Cross Section for Precise Determination of Neutrino Beam Properties in T2K Oscillation Experiment Magdalena Zofia Posiadała Ph.D. thesis written under supervision of prof. dr hab. Danuta Kiełczewska Warsaw, 2011 Abstract Differential cross sections and mean multiplicities in production processes for low momentum charged pion mesons and protons in p+C interactions at 31 GeV/c measured with the large acceptance NA61/SHINE spectrometer at the CERN SPS are presented. A set of data col- lected during the first NA61/SHINE run in 2007 with a thin graphite target was used for the analysis. The results are presented as a function of laboratory momentum in 10 intervals of the laboratory polar angle covering the range from 0 up to 420 mrad. The spectra are compared with predictions of several hadron production models. Measurements for π+ and π− mesons are used by the T2K experiment to tune neutrino beam simulations and reduce uncertainties on charged pion production.

Measurement of Hadron-Carbon Interactions for Better Understanding of Air Showers with NA61/SHINE
33RD INTERNATIONAL COSMIC RAY CONFERENCE,RIO DE JANEIRO 2013 THE ASTROPARTICLE PHYSICS CONFERENCE Measurement of hadron-carbon interactions for better understanding of air showers with NA61/SHINE H. P. DEMBINSKI1 FOR THE NA61/SHINE COLLABORATION2. 1 Institut fur¨ Kernphysik, KIT Karlsruhe, Postfach 3640, D - 76021 Karlsruhe 2 Full author list: https: // na61. web. cern. ch/ na61/ pages/ storage/ authors_ list. pdf [email protected] Abstract: The interpretation of air shower measurements requires the detailed simulation of hadronic particle production over a wide range of energies and the forward phase space of secondary particles. In air showers, the bulk of particles is produced at later stages of the shower development and at equivalent beam energies in the sub-TeV range. NA61/SHINE is a fixed target experiment using secondary beams produced at the SPS at 1 CERN. Hadron-hadron interactions have been recorded at beam momenta between 13 and 350 GeVc− with a wide-acceptance spectrometer. In this article we present measurements of the inelastic cross-section and secondary particle yields of pion-carbon interactions, which are essential for modelling air showers. Keywords: hadron interaction, QCD, air shower, pion 1 Hadronic interactions in air showers Cosmic rays initiate extensive air showers (EAS) when they collide with nuclei of the atmosphere. The EAS data recorded by experiments like the Pierre Auger Observa- tory [1], KASCADE [2] or IceTop [3], is used to infer their properties. The interpretation relies on simulations of the shower development during which electromagnetic and hadronic particle interactions are followed from primary 20 9 energies of & 10 eV down to energies of 10 eV. -
Cosmic-Ray Studies with Experimental Apparatus at LHC

San Claudio y 18 Sur, Edif. EMA3-231, Ciudad Universitaria, 72570 Puebla, Mexico; [email protected] (E.G.H.); [email protected] (A.F.T.) 2 Instituto de Física y Matemáticas, Universidad Michoacana, 58040 Morelia, Mexico; [email protected] * Correspondence: [email protected] Received: 11 September 2020; Accepted: 2 October 2020; Published: 15 October 2020 Abstract: The study of cosmic rays with underground accelerator experiments started with the LEP detectors at CERN. ALEPH, DELPHI and L3 studied some properties of atmospheric muons such as their multiplicity and momentum. In recent years, an extension and improvement of such studies has been carried out by ALICE and CMS experiments. Along with the LHC high luminosity program some experimental setups have been proposed to increase the potential discovery of LHC. An example is the MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles detector (MATHUSLA) designed for searching of Ultra Stable Neutral Particles, predicted by extensions of the Standard Model such as supersymmetric models, which is planned to be a surface detector placed 100 meters above ATLAS or CMS experiments. Hence, MATHUSLA can be suitable as a cosmic ray detector. In this manuscript the main results regarding cosmic ray studies with LHC experimental underground apparatus are summarized. The potential of future MATHUSLA proposal is also discussed. Keywords: cosmic ray physics at CERN; atmospheric muons; trigger detectors; muon bundles 1. -
The Cell Geometry Is Adapted to the Manufacturing Process. One Side Of
R&D for the Future 443 The cell geometry is adapted to the manufacturing process. One side of the cell carries all the features required for the RF, whereas the other side is flat for bonding (Fig. 12.11). The cells are diamond machined, joined by diffusion bonding under hydrogen at about 1000°C and vacuum baked at 650°C. With exacting machining tolerances, typically in the 1 µm range, the tuning of the final structure is avoided. A number of test facilities is in operation worldwide including those at CERN which houses the only facility modelling the two-beam scheme in addition to a number of test stands powered by klystrons for high turn-around of testing structure variants. Nominal accelerating gradients of 100 MV/m have been achieved in the accelerating structures under development in a worldwide collaboration with the required low break-down rate while the PETSs have been tested at the nominal output power of 150 MW. However, more variants of these two structures have to be built and examined to address HOM damping, lifetime, breakdown statistics, industrial-scale fabrication, and better understanding of the break-down mechanisms. The Next Energy Frontier e+e− Collider: Innovation in Detectors Lucie Linssen Throughout the history of particle physics, both protons and electrons, with their respective antiparticles, have been used extensively for high energy colliders [Box 4.1]. The merits and difficulties of physics research with high luminosity proton–proton colliders are briefly described in the Box 8.3. Electrons, in contrast to protons, are genuine elementary particles. Apart from initial-state radiation and beamstrahlung effects (see below), they provide very good knowledge of the initial state of the collision. -
