PRODUCTION OF DRELL--YAN PAIRS IN HIGH ENERGY NUCLEON--NUCLEON COLLISIONS

We compute cross sections for the Drell-Yan process in N--N collisions at next-to-leading order in $α_s$. The mass, rapidity, transverse momentum, and angular dependence of these cross sections are presented. An estimate of higher order corrections is obtained from next-to-next-to-leading order calculation of the mass distribution. We compare the results with some of the existing data to show the quality of the agreement between calculations and data. We present predictions for energies which will become available at the RHIC and LHC colliders. Uncertainties in these predictions due to choices of scale, scheme and parton distribution are discussed.

Formation Time Scales for Quarkonia in a Deconfining Medium

Production of heavy quark antiquark systems in high energy heavy ion collisions must involve relativistic momentum components in a quantum mechanical approach. If the color forces are screened in a deconfining medium, one can define the analog of a formation or separation time by an overlap integral in the nonrelativistic bound state rest frame. This time parameter has some interesting properties which depend on the momentum spectrum of the initial quarks. Consequences of these properties for the phenomenology of deconfinement signals are discussed.
