This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: D[O] has used W[yields] e[nu] and Z[yields] e[sup+]e[sup -] events produced in association with a high p[sub T], jet to examine the effects of strong radiative corrections. We have compared the primary jet pseudorapidity distribution, as a function of reconstructed W or Z boson rapidity to leading order (LO) and Next-to-Leading order (NLO) QCD Monte Carlo generators, as well as a model based on extended color dipoles. We find that the primary jet is more central than either LO or NLO expectations. None of the Monte Carlo programs does a good job of predicting the shape of the jet distributions as a function of intermediate vector bosons rapidity.

This book was released on 2016 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, the quark-gluon plasma is studied via medium-induced changes to correlations between jets and charged particles in PbPb collisions compared to pp reference data. This analysis uses data sets from PbPb and pp collisions with integrated luminosities of 166 inverse microbarns and 5.3 inverse picobarns, respectively, collected at $ \sqrt{s_{\mathrm{NN}}}=2.76 $ TeV. The angular distributions of charged particles are studied as a function of relative pseudorapidity ([Delta][eta]) and relative azimuthal angle ([Delta][Phi]) with respect to reconstructed jet directions. Charged particles are correlated with all jets with transverse momentum (pT) above 120 GeV, and with the leading and subleading jets (the highest and second-highest in pT, respectively) in a selection of back-to-back dijet events. Modifications in PbPb data relative to pp reference data are characterized as a function of PbPb collision centrality and charged particle pT. A centrality-dependent excess of low-pT particles is present for all jets studied, and is most pronounced in the most central events. This excess of low-pT particles follows a Gaussian-like distribution around the jet axis, and extends to large relative angles of [Delta][eta] ≈ 1 and [Delta][Phi] ≈ 1.

Available in PDF, EPUB and Kindle. Book excerpt: QCD motivated polarized parton distributions, evolved directly in x-space, are used to predict rates for prompt photon and jet production at RHIC and HERA-N center of mass energies. Various scenarios for the polarized gluon distributions are considered and compared, and the possibility of using large p{sub T} processes in polarized pp collision experiments to choose between them is analyzed.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cross section for inclusive jet production in high-energy pp collisions is well described by pQCD in the collinear factorization framework, which, together with its high rate and clear signal, makes it a key observable to study the proton structure. For pp collisions at RHIC at a center-of-mass energy of √s = 200 GeV, the STAR detector provides jet measurements at 0.07 ≲ xT ≡ 2pT:jet/√s ≲ 0.5. At these kinematics, the direct scattering on gluons inside the colliding protons contributes at least half of the total jet production cross section. Measurements of the inclusive jet cross section at RHIC, together with the past Deep Inelastic Scattering measurements, can provide improved constraints on the gluon Parton Distribution Function at high x.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We report a new measurement of the midrapidity inclusive jet longitudinal double-spin asymmetry, ALL, in polarized pp collisions at center-of-mass energy √s = 200 GeV. The STAR data place stringent constraints on polarized parton distribution functions extracted at next-to-leading order from global analyses of inclusive deep-inelastic scattering (DIS), semi-inclusive DIS, and RHIC pp data. Lastly, the measured asymmetries provide evidence at the 3? level for positive gluon polarization in the Bjorken-x region x > 0.05 .
