This book was released on 2012-12-06 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ninth Advanced Study Institute (AS!) on Techniques and Concepts of High Energy Physics was almost canceled before ifbegan! A certain visitor to the area (Hurricane Bertha) arrived unexpectedly early in 1996. It was the first hur ricane in memory to menace the Caribbean in early July! Fortunately, it passed St. Croix several days before our meeting, and left very little damage. (The Altar ellis survived the eye of the storm in the in the British West Islands!) The meeting was held once again at the hotel on the Cay, on that spec of land in the harbor ofChrirtiansted, St. Croix, U. S. Virgin Islands. After the first two days of, at times, outrageous downpour, the 71 participants from 26 coun tries began to relax and enjoy the lectures and the lovely surroundings of the In stitute. The primary support for the meeting was provided by the ~cientific Affairs Division of the North Atlantic Treaty Organization (NATO). The ASI was cosponsored by the U. S. department of Energy, by the Fermi National Accelera tor Laboratory (Fermi-lab), by the U. S. National Science Foundation, and by the University of Rochester. In addition, the International Science Foundation con tributed to the support of a participant from Russia. As in the case of the previous ASIs, the scientific program was designed for advanced graduate students and recent Ph. D. recipients in experimental parti cle physics.

This book was released on 2004-08-10 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possible upgrade of LHC or a future generation of colliders at the extreme limits of energy and luminosity will require detectors based on very advanced technological solutions to fully exploit the physics opportunities offered. Major steps must be taken to design and realize devices that are able not only to handle very high rates but also to cope with the very harsh radiation environment without suffering any performance degradation.This book reviews the present status, current limits and recent developments in detection techniques and related aspects (simulation, signal acquisition, tracking, particle identification, etc.). Novel ideas in this domain are discussed with emphasis on the directions in which improvements in proven techniques are desired.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)• CC Proceedings — Engineering & Physical Sciences

Download or read book Sources of Machine-induced Background in the ATLAS and CMS Detectors at the CERN Large Hadron Collider written by and published by . This book was released on 2013 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: One source of experimental background in the CERN Large Hadron Collider (LHC) is particles entering the detectors from the machine. These particles are created in cascades, caused by upstream interactions of beam protons with residual gas molecules or collimators. We estimate the losses on the collimators with SixTrack and simulate the showers with FLUKA and MARS to obtain the flux and distribution of particles entering the ATLAS and CMS detectors. We consider some machine configurations used in the first LHC run, with focus on 3.5 TeV operation as in 2011. Results from FLUKA and MARS are compared and a very good agreement is found. An analysis of logged LHC data provides, for different processes, absolute beam loss rates, which are used together with further simulations of vacuum conditions to normalize the results to rates of particles entering the detectors. We assess the relative importance of background from elastic and inelastic beam-gas interactions, and the leakage out of the LHC collimation system, and show that beam-gas interactions are the dominating source of machine-induced background for the studied machine scenarios. Our results serve as a starting point for the experiments to perform further simulations in order to estimate the resulting signals in the detectors.

Book Synopsis Secondary Particle in Background Levels and Effects on Detectors at Future Hadron Colliders by :
Download or read book Secondary Particle in Background Levels and Effects on Detectors at Future Hadron Colliders written by and published by . This book was released on 1993 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The next generation of hadron colliders, the Superconducting Super Collider (SSC) and the Large Hadron Collider (LHC), will operate at high center-of-mass energies and luminosities. Namely, for the SSC (LHC) (square root)s = 40 TeV ((square root)s = 16 TeV) and L = 1033 cm−2s−1 (L = 3 x 1034 cm−2s−1). These conditions will result in the production of large backgrounds as well as radiation environments. Ascertaining the backgrounds, in terms of the production of secondary charged and neutral particles, and the radiation environments are important considerations for the detectors proposed for these colliders. An initial investigation of the radiation levels in the SSC detectors was undertaken by D. Groom and colleagues, in the context of the ''task force on radiation levels in the SSC interaction regions.'' The method consisted essentially of an analytic approach, using standard descriptions of average events in conjunction with simulations of secondary processes. Following Groom's work, extensive Monte Carlo simulations were performed to address the issues of backgrounds and radiation environments for the GEM and SD C3 experiments proposed at the SSC, and for the ATLAS and CMS experiments planned for the LHC. The purpose of the present article is to give a brief summary of some aspects of the methods, assumptions, and calculations performed to date (principally for the SSC detectors), and to stress the relevance of such calculations to the detectors proposed for the study of B-physics in particular.

Book Synopsis Higgs Puzzle, The: What Can We Learn From Lep2, Lhc, Nlc, And Fmc? - Proceedings Of The 1996 Ringberg Workshop by : Bernd A Kniehl
Download or read book Higgs Puzzle, The: What Can We Learn From Lep2, Lhc, Nlc, And Fmc? - Proceedings Of The 1996 Ringberg Workshop written by Bernd A Kniehl and published by World Scientific. This book was released on 1997-07-15 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the great success of the standard model of electroweak and strong interactions to describe the phenomena observed in high energy physics experiments, the mechanism by which the elementary particles are endowed with their masses is yet to be unraveled. Does nature choose the Higgs mechanism of spontaneous symmetry breaking as predicted by the standard model, or do we need some alternative explanation? The purpose of the workshop is to capture new trends and ideas in this exciting area of fundamental physics, and to explore the potential of recent (LEPI), present (HERA, LEPII, SLC, Tevatron), and future (FMC, LHC, NLC) colliding-beam experiments to shed light on the Higgs puzzle.
Book Synopsis Photon Physics at the LHC by : Michael Hance
Download or read book Photon Physics at the LHC written by Michael Hance and published by Springer. This book was released on 2012-11-09 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports on the first studies of Standard Model photon production at the Large Hadron Collider (LHC) using the ATLAS detector. Standard Model photon production is a large background in the search for Higgs bosons decaying into photon pairs, and is thus critical to understand. The thesis explains the techniques used to reconstruct and identify photon candidates using the ATLAS detector, and describes a measurement of the production cross section for isolated prompt photons. The thesis also describes a search for the Higgs boson in which the analysis techniques used in the measurement are exploited to reduce and estimate non-prompt backgrounds in diphoton events.

Available in PDF, EPUB and Kindle. Book excerpt: The rich physics potential of a high-energy high-luminosity??− collider and the surprising feasibility of a design attract the attention of many people these days. A few issues define the practicality of such a project, with the enormous particle background levels in a detector due to unavoidable reasons holding first place. In contrast to hadron colliders where particle backgrounds come both from interaction point (IP) and accelerator, almost all the backgrounds in the muon collider detectors arise in the machine. The decay length for 2 TeV muons is?{sub D}−1 -10−7 m−1. With 1012 muons in a bunch one has 105 decays per meter in a single pass through an interaction region, and 108 decays per meter per 12 msec store. This paper examines two major classes of detector backgrounds presented in the muon collider: beam halo backgrounds, and the {open_quotes}direct{close_quotes} backgrounds from electrons from????????e?{bar {nu}} decay occurring in the beam channel. The authors describe the nature of both of these backgrounds, provide results of first realistic calculations for both sources and discuss their effects on plausible detectors. Various shielding and collimation geometries have been simulated, and their efficacy and the nature of the surviving background discussed.
