Book excerpt: We have studied the[ital J]/[psi] production in[ital p][ital[anti p]] collisions at[radical]s= 1.8 TeV with the D[null] detector at the Fermilab Tevatron, using a[mu][sup+][mu][sup -] data sample collected during the 1994-95 running period. We have measured the inclusive[ital J]/[psi] production cross section as a function of the[ital J]/[psi] transverse momentum, [ital P][sub T][sup[ital J]/[psi]] in the central and forward rapidity regions. The new measurement of the cross section[ital d[sigma]/dp][sub T][sup[ital J]/[psi]] for[vert-bar][eta][sup[ital J]/[psi]][vert-bar][lt] 0.6 is in a good agreement with the CDF and earlier D[null] results. The cross section measurement[ital d[sigma]/dp][sub T][sup[ital J]/[psi]] for 2.5[lt][vert-bar][eta][sup[ital J]/[psi]][vert-bar][lt] 3.7 covers the[ital p][sub T][sup[ital J]/[psi]] range from 1 to 16 GeV/c. We combine the measurements in several[vert-bar][eta][sup[ital J]/[psi]][vert-bar] regions to discuss[ital d[sigma]/d[eta]][sup[ital J]/[psi]] for[ital p][sub T][sup[ital J]/[psi]][gt] 8 GeV/c. The data are compared with the next-to- leading order (NLO) QCD calculations, which take into account different[ital J]/[psi] production mechanisms.

This book was released on 2010-03-24 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an introduction to main ideas used in the physics of ultra-relativistic heavy-ion collisions. The links between basic theoretical concepts (discussed gradually from the elementary to more advanced level) and the results of experiments are outlined, so that experimentalists may learn more about the foundations of the models used by them to fit and interpret the data, while theoreticians may learn more about how different theoretical ideas are used in practical applications. The main task of the book is to collect the available information and establish a uniform picture of ultra-relativistic heavy-ion collisions. The properties of hot and dense matter implied by this picture are discussed comprehensively. In particular, the issues concerning the formation of the quark-gluon plasma in present and future heavy-ion experiments are addressed.

This book was released on 2011 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have carried out a wide study of Cold Nuclear Matter (CNM) effects on J/[Psi] = production in dAu, CuCu and AuAu collisions at √s{sub NN} = 200 GeV. We have studied the effects of three different gluon-shadowing parameterizations, using the usual simplified kinematics for which the momentum of the gluon recoiling against the J/[Psi] is neglected as well as an exact kinematics for a 2 → 2 process, namely g + g → J/[psi] + g as expected from LO pQCD. We have shown that the rapidity distribution of the nuclear modification factor R{sub dAu}, and particularly its anti-shadowing peak, is systematically shifted toward larger rapidities in the 2 → 2 kinematics, irrespective of which shadowing parameterization is used. In turn, we have noted differences in the effective final-state nuclear absorption needed to fit the PHENIX dAu data. Taking advantage of our implementation of a 2 → 2 kinematics, we have also computed the transverse momentum dependence of the nuclear modification factor, which cannot be predicted with the usual simplified kinematics. All the corresponding observables have been computed for CuCu and AuAu collisions and compared to the PHENIX and STAR data. Finally, we have extracted the effective nuclear absorption from the recent measurements of RCP in dAu collisions by the PHENIX collaboration.
