Available in PDF, EPUB and Kindle. Book excerpt: A measurement of the J/psi and psi(2S) production cross sections in pp collisions at sqrt(s)=7 TeV with the CMS experiment at the LHC is presented. The data sample corresponds to an integrated luminosity of 37 inverse picobarns. Using a fit to the invariant mass and decay length distributions, production cross sections have been measured separately for prompt and non-prompt charmonium states, as a function of the meson transverse momentum in several rapidity ranges. In addition, cross sections restricted to the acceptance of the CMS detector are given, which are not affected by the polarization of the charmonium states. The ratio of the differential production cross sections of the two states, where systematic uncertainties largely cancel, is also determined. The branching fraction of the inclusive B to psi(2S) X decay is extracted from the ratio of the non-prompt cross sections to be: BR(B to psi(2S) X) = (3.08 +/- 0.12(stat.+syst.) +/- 0.13(theor.) +/- 0.42(BR[PDG])) 10-̂3.

Available in PDF, EPUB and Kindle. Book excerpt: The production of J/psi mesons is studied in pp collisions at sqrt(s)=7 TeV with the CMS experiment at the LHC. The measurement is based on a dimuon sample corresponding to an integrated luminosity of 314 inverse nanobarns. The J/psi differential cross section is determined, as a function of the J/psi transverse momentum, in three rapidity ranges. A fit to the decay length distribution is used to separate the prompt from the non-prompt (b hadron to J/psi) component. Integrated over J/psi transverse momentum from 6.5 to 30 GeV/c and over rapidity in the range.

Book excerpt: This paper reports the measurement of J/psi meson production in proton-proton (pp) and proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of 5.02 TeV by the CMS experiment at the LHC. The data samples used in the analysis correspond to integrated luminosities of 28 inverse picobarns and 35 inverse nanobarns for pp and pPb collisions, respectively. Prompt and nonprompt J/psi mesons, the latter issuing from the decay of B mesons, are measured in their dimuon decay channels. Differential cross sections are measured in the transverse momentum range of 2

Book excerpt: We study J/[psi] production at RHIC and LHC energies with both initial production and regeneration. We solve the coupled set of transport equation for the J/[psi] distribution in phase space and the hydrodynamic equation for evolution of quark-gluon plasma. At RHIC, continuous regeneration is crucial for the J/[psi] momentum distribution while the elliptic flow is still dominated by initial production. At LHC energy, almost all the initially created J/[psi]s are dissociated in the medium and regeneration dominates the J/[psi] properties.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the first J/psi production analysis of Au+Au reactions at forward rapidity at [square root]sNN = 200 GeV. In the second year of RHIC running, design energy was achieved in the collisions of both Au+Au ions and proton+proton reactions. The production of the J/psi is measured by the PHENIX experiment in Au+Au collisions as well as in proton-proton collisions. The scientific goal is to investigate the nature of hot, dense nuclear matter capitalizing on the unique properties of the J/psi as a probe of this matter. Recent experimental results by the NA50 collaboration at CERN strongly deviate from the conventional picture that successfully describes data at lower energies. The importance of such a measurement is demonstrated by the wide spectrum of theoretical explanations concerning the existing data. The merits of these models will be explored in a systematic and comprehensive study of the J/psi and open charm in collisions of a variety of species and energy. A survey of the theoretical models is presented and the relevant open charm and J/psi PHENIX measurements are compared.

Download or read book Measurement of the Prompt Double J/psi Production Cross Section in Pp Collisions at Sqrt(s) written by Andrew David York and published by . This book was released on 2013 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: The simultaneous production of two J/psi mesons has been significantly observed in proton-proton collisions at a center-of-mass energy of 7 TeV with the CMS detector. The two J/psi mesons are fully reconstructed in their decay to muons. The signal yield is extracted with an extended maximum likelihood fit based on four event variables. A method was developed to correct for detector acceptances and efficiencies based on the measured momenta of the J/psi and their decay muons to maintain the least model dependence possible. The measurement is performed in an acceptance region defined by the individual J/psi transverse momentum and rapidity. From the measured signal yield of 446 events corresponding to an integrated luminosity of 4:7 inverse femtobarn. The total cross section is found to be 1:49 nanobarn, with 0:07 statistical and 0:13 nb systematic error, and unpolarizaed production was assumed. Most predictions for particle production at the LHC assume dominance of single parton interaction for proton-proton collisions, which can be tested with the final state measured in this analysis. The differential cross section is measured in bins of the double J/psi invariant mass, the double J/psi transverse momentum, and the absolute difference in rapidity of the two J/psi. The reconstruction of the four charged muon trajectories heavily relies on the Pixel subdetector located close to the beampipe. Systematic studies with cosmic muons and tracks from collision events are presented. The development of the Pixel RawToDigi package, data quality monitoring packages, commissioning studies of Pixel data and tracks in first collisions, and realistic simulations of decay signals in the pixel subdetector were all performed as a part of this dissertation work.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum Chromodynamics predicts that the hot and dense matter produced in ultra-relativistic heavy-ion collisions, the Quark Gluon Plasma (QGP), behaves as a deconfined state of quarks and gluons. Since 1980's it was predicted that quarkonia are suppressed due to screening effects in the QGP, making quarkonia a good tool to probe the plasma.ALICE is the only experiment at the LHC that was designed and built to characterize the physics of the QGP. The muon spectrometer, one of the detectors in ALICE, is used to measure the quarkonia production at forward rapidity. In this thesis the efficiency of the tracking chambers of the muon spectrometer is studied along one year of data taking. The results obtained from real data are compared to simulations in order to compute the systematic uncertainties associated to the tracking apparatus.A complete analysis of the inclusive J/psi --> mu^+ mu^- production in the 2011 Pb-Pb collisions is also presented. The study includes the signal extraction, normalization and acceptance times efficiency corrections. An important part is dedicated to the quantify the systematic uncertainties arising from different sources. The resulting R_{AA} and p_{T} are compared to previous experiments and also to theoretical models.
