Charmonium production in polarized high-energy collisions
We investigate the inclusive production of prompt J/ψ mesons in polarized hadron-hadron, photon-hadron, and photon-photon collisions in the factorization formalism of nonrelativistic quantum chromodynamics (NRQCD) providing all contributing partonic cross sections in analytic form. In the case of photoproduction, we also include the resolved-photon contributions. We present numerical results ap...
متن کاملCharmonium Polarization in High Energy Collisions
We consider charmonium polarization at high-energy hadron collider Tevatron in the framework of the nonrelativistic QCD (NRQCD) and the kT -factorization approach. The polarization effects are studied for the direct and the prompt production channels. The obtained predictions can be used for test of the Regge limit of QCD and for test of the NRQCD formalism. High-energy factorization In the phe...
متن کاملCharmonium Production in High Energy Collisions
One motivation for studying the production of charmonium in high energy collisions is that these particles are among the simplest probes for heavy-ion collisions. In recent years, there have been significant developments in heavy quarkonium production, both in theory and in experiment. These developments may have important implications for the use of charmonium as a probe in heavy-ion collision...
متن کاملCharmonium Suppression in Nuclear Collisions
Has the quark gluon plasma been discovered at the CERN SPS? Experiment NA50 has reported an abrupt decrease in ψ production in Pb+Pb collisions at 158 GeV per nucleon [1]. Specifically, the collaboration presented a striking ‘threshold effect’ in the ψ–to–continuum ratio by plotting it as a function of a calculated quantity, the mean path length of the ψ through the nuclear medium, L, as shown ...
متن کاملModeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
