Download or read book Measurement of the Prompt J/Psi Pair Production Cross Section in Pp Collisions at Sqrt(s) written by Grant Valentine Riley and published by . This book was released on 2017 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cross section for the prompt production of [J/Psi] meson pairs in proton-proton collisions at √ s[sqrt(s)] = 8 TeV at the LHC from a sample corresponding to an integrated luminosity of 20.2±0.5 fb−1 [inverse femtobarns] has been measured with the CMS detector. It provides unique insight into particle production and proton structure in proton-proton (pp) collisions. The two [J/Psi] mesons are fully reconstructed in their [mu+ mu-] decay. An acceptance region is defined by the individual [J/Psi] transverse momentum p [J/Psi pT] and rapidity y [J/Psi Rapidity]. The total fiducial cross section assuming unpolarized prompt [J/Psi] pair production is found to be [sigma_fid] = 195.7 ± 11.1 (stat) ± 22.1 (syst) ± 5.1 (lumi) ± 2.3 (BF) pb. The differential cross sections for prompt [J/Psi] pair production within this acceptance region are measured in eight event variables. Most predictions for particle production in pp collisions at the LHC assume dominance of single parton (gluon, quark) interactions (SPS) at the leading order perturbation theory. This assumption is tested with the final state measured in this analysis. Significant contributions from next-to-leading order processes and double parton scattering (DPS) are observed. In addition, the single [J/Psi] production cross section is estimated from theory and measured with pp collision data. Single [J/Psi] production is compared to the pair production via DPS and quantified via an effective cross section. This quantity is further compared to several particle pair production processes. In particular, the [J/Psi] pair production probes the contributions of gluons. All particle production measurements with CMS depend on the precise knowledge of the LHC luminosity. A detector, the Pixel Luminosity Telescope, based on solid state technology is used to count charged particle tracks from pp collisions, a measure of the instantaneous luminosity. The measurement is provided online for every crossing of the LHC beams. Tests of sensors and the development work for the detector are presented.

This book was released on 1997 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of prompt photon plus associated jet production is performed at next-to-leading order (O([alpha][alpha]{sub s}2)) in QCD at √S = 200--500 GeV, appropriate for the RHIC polarized {rvec p}{rvec p} collider experiment. Momentum correlations between the jet and photon are examined and the utility of the process as a method for constraining the size and shape of the polarized gluon density of the proton [Delta]G is examined.

Available in PDF, EPUB and Kindle. Book excerpt: Production of prompt J/[psi] meson pairs in proton-proton collisions at √s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb-1. The two J/[psi] mesons are fully reconstructed via their decays into [mu] + [mu] - pairs. This observation provides for the first time access to the high-transverse-momentum region of J/[psi] pair production where model predictions are not yet established. The total and differential cross sections are measured in a phase space defined by the individual J/[psi] transverse momentum (p T J/[psi] ) and rapidity (

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.
