Book excerpt: Presented are the most recent jet fragmentation results from CDF: inclusive distributions of charged particle momenta and their k{sub T} in jets; average track multiplicities, as well as angular distributions of multiplicity flow, for a wide range of jet energies with E{sub T} from 40 to 300 GeV. The results are compared with Monte-Carlo and, when possible, analytical calculations performed in resumed perturbative QCD approximations (MLLA).

Book excerpt: In this paper, the most recent results on jet fragmentation obtained at the Collider Detector at Fermilab Tevatron are presented. The multiplicity and momentum distribution of charged particles inside jets in dijet events are compared to the predictions of the Modified Leading Log Approximation complemented with the hypothesis of Local Parton-Hadron Duality. Values for the two parameters of the model are extracted, the cut-off scale Q[sub eff]= 230[+-] 40 MeV and the rate of parton-to-hadron conversions K[sub LPHD][sup charged]= 0.56[+-] 0.10. A fit of the data for the ratio of multiplicities in gluon and quark jets r, where r is treated as a free parameter, results in r= 1.9[+-] 0.5. Also, we compare the charged particle multiplicities in dijet and[gamma]-jet events. The comparison allows for an extraction of a model-independent ratio of multiplicities in gluon and quark jets. We report r= N[sub g]/N[sub q]= 1.61[+-] 0.11(stat)[+-] 0.28(syst) for E[sub jet]= 40 GeV.

Book Synopsis Jet physics in ALICE by : Constantin Loizides
Download or read book Jet physics in ALICE written by Constantin Loizides and published by ibidem-Verlag / ibidem Press. This book was released on 2012-02-03 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ALICE experiment is one of the experiments currently prepared for the Large Hadron Collider (LHC) at CERN, Geneva, starting operation end of 2007. ALICE is dedicated to the research on nucleus-nucleus collisions at ultra-relativistic energies, which addresses the properties of strongly interacting matter under varying conditions of high density and temperature. The conditions provided at the LHC allow significant qualitative improvement with respect to previous studies. In particular, energetic probes, light quarks and gluons, will be abundantly produced. These probes might be identified by their fragmentation into correlated particles, so called jets, of high enough energy to allow full reconstruction of jet properties; even in the underlying heavy-ion environment.Understanding the dependence of high-energy jet production and fragmentation influenced by the dense medium created in the collision region is an open field of active research. Generally, one expects energy loss of the probes due to medium-induced gluon radiation. It is suggested that hadronization products of these, rather soft gluons may be contained within the jet emission cone, resulting in a modification of the characteristic jet fragmentation, as observed via longitudinal and transverse momentum distributions with respect to the direction of the initial parton, as well as of the multiplicity distributions arising from the jet fragmentation. Particle momenta parallel to the jet axis are softened (jet quenching), while transverse to it increased (transverse heating). The present thesis studies the capabilities of the ALICE detectors to measure these jets and quantifies obtainable rates and the quality of jet reconstruction, in both proton-proton and lead-lead collisions at the LHC. In particular, it is addressed whether modification of the jet fragmentation can be detected within the high-particle-multiplicity environment of central lead-lead collisions.

Download or read book Fragmentation Properties of Jets Produced in Proton-antiproton Collisions at Radical S written by and published by . This book was released on 1989 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jet fragmentation properties have been studied in collisions of protons and antiprotons at a center-of-mass energy of 1.8 TeV, using the Collider Detector at Fermilab (CDF). The fractional momentum distribution of charged particles within jets is presented and compared with Monte-Carlo predictions. With increasing di-jet invariant mass from 60 to 200 GeV/c2 the fragmentation is observed to soften as predicted by scale breaking effects in Quantum Chromodynamics (QCD). The charged multiplicity in the jet core is observed to rise with di-jet invariant mass. 57 refs.

Book Synopsis EPS - High Energy Physics '89 by : R. Fernandez Alvarez-Estrada
Download or read book EPS - High Energy Physics '89 written by R. Fernandez Alvarez-Estrada and published by Elsevier. This book was released on 2016-06-03 with total page 729 pages. Available in PDF, EPUB and Kindle. Book excerpt: EPS - High Energy Physics '89 presents the proceeding of the International Europhysics Conference on High Energy physics, held in Madrid, Spain, on September 6–13, 1989. This book outlines several topics on the interface between cosmology/astrophysics and particle physics. Organized into two parts encompassing 181 chapters, this compilation of papers begins with an overview of the implications of the cosmic light element abundances. This text then examines the various aspects of lattice field theory. Other chapters consider the theoretical evidence of a fundamental length in string theory and outline the main features of the higher order corrections to the heavy quark inclusive cross section. This book discusses as well the theory of heavy quark production in hadron collision. The final chapter deals with the idea of low-energy supersymmetry, which relates the scale of supersymmetry breaking to the origin and stability of the electroweak scale. This book is a valuable resource for astrophysicists, physicists, and scientists.

Book excerpt: At the Fermilab Tevatron energies, ((square root) s=1800 GeV and (square root) s = 630 GeV), jet production is the dominant process. During the period 1992-1996, the D0 and CDF experiments accumulated almost 100 pb−1 of data and performed the most accurate jet production measurements up to this date. These measurements and the NLO-QCD theoretical predictions calculated during the last decade, have improved our understanding of QCD, our knowledge of the proton structure, and pushed the limit to the scale associated with quark compositeness to 2.4-2.7 TeV. In this paper, we present the most recent published and preliminary measurements on jet production and fragmentation by the D0 and CDF collaborations.

Download or read book Particle Physics: Perspectives And Opportunities - Report Of The Dpf Committee On Long-term Planning written by Robert N Cahn and published by World Scientific. This book was released on 1995-09-20 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of a broad-based and in-depth study of high energy physics commissioned by the Executive Committee of the Division of Particles and Fields of the American Physical Society. This year-long study was initiated in the early 1994, in the wake of the cancellation of the SSC, and is meant to complement the report of the Drell HEPAP subpanel, charged with providing a vision for the future of the field. The DPF study of high energy physics was organized on the basis of the working groups, each led by a number of co-conveners chosen among established leaders in the various subspecialties in the field. These conveners, in turn, organized their working groups by inviting other active workers in the discipline to participate and gathered further input from the community by holding a variety of specialized meetings and workshops. This book contains the final reports of the 11 working groups assembled for the study, along with an extended overview and executive summary by the editors.
