Two–spin Asymmetry of Heavy Quarkonia Productions at Rhic Energy
Hadroproductions of charmonium and bottomonium χJ in polarized pp collisions at RHIC energies are studied. Two–spin asymmetries AJ LL(pp) for these reactions are very good parameters for examining the polarized gluon distributions in a proton.
متن کاملMC-Simulation of the Transverse Double Spin Asymmetry for RHIC∗
Using Sphinx tt, a new MC simulation program for transverse polarized nucleon–nucleon scattering based on Pythia 5.6, we calculate the transverse double spin asymmetry ATT in the Drell-Yan process. If one assumes (quite arbitrarily) that the transversity parton distribution δq(x,Q2) equals the helicity distribution ∆q(x,Q2) at some low Q0 scale, the resulting asymmetry is of order 1%. In this c...

RHIC began operation in 2000, culminating over ten years of development and construction and a much longer period of theoretical speculations about the properties of hot QCD matter produced in nuclear collisions in the collider regime. This Conference presents a good occasion to look at the first experimental results and to discuss their meaning and significance. It is also time to think about ...

Hydrodynamical models have certain advantages over transport model calculations in describing heavy ion collisions. One of the most important is that, once the equation of state and initial conditions of the matter are specified, the evolution of the system is determined. No knowledge of the underlying microscopic processes is required. This is especially important when studying the predicted p...
متن کاملLongitudinal Spin Asymmetry and Cross Section of Inclusive π0 Production in Polarized p+ p Collisions at RHIC
We present the first measurement of the cross section and the double longitudinal spin asymmetry of inclusive π0 production in polarized p+p collisions at √ s = 200 GeV at mid-rapidity with the STAR detector, using the barrel electromagnetic calorimeter. The measured cross section is compared to NLO pQCD calculations and can provide constraints on the pion fragmentation functions. Fragmentation...
