MC-Simulation of the Transverse Double Spin Asymmetry for RHIC∗
نویسندگان
چکیده
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 case is ATT would hardly be be measurable with PHENIX at RHIC. ∗UFTP 417 preprint/96

Transverse Double-Spin Asymmetries for Dimuon Production in pp Collisions
We calculate the transverse double-spin asymmetry for the production of dimuons in pp collisions as function of the dimuon rapidity and mass to next-to-leading order accuracy in the strong coupling constant. Predictions for Bnl-Rhic and Hera~ N are made by assuming a saturation of Soffer’s inequality at a low hadronic input scale. It seems unlikely that transversity can be measured in dimuon pr...
متن کامل5 Phenix Spin Program , Recent Results
Acceleration of polarized protons in Relativistic Heavy Ion Collider (RHIC) provides unique tool to study the spin structure of the nucleon. We give a brief overview of the PHENIX program to investigate poorly known gluon and flavor decomposed see quark polarization in the proton, utilizing polarized proton collisions at RHIC. We report PHENIX first results on transverse single-spin asymmetry i...
متن کاملThe Gluon Sivers Distribution in D Production at Rhic
The single transverse spin asymmetry in D meson production at RHIC can provide a clean measure of the gluon Sivers distribution function. At intermediate rapidity, D production is largely dominated by the elementary gg → cc̄ channel, where there cannot be any transverse spin transfer. Therefore, any transverse single spin asymmetry observed for D’s produced in pp interactions can only originate ...

The STAR experiment at the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) is carrying out a spin physics program colliding transverse or longitudinal polarized proton beams at √ s = 200−500GeV to gain a deeper insight into the spin structure and dynamics of the proton. These studies provide fundamental tests of Quantum Chromodynamics (QCD). One of the main object...
متن کاملConstraints on ∆G through Longitudinal Double Spin Asymmetry Measurements of Inclusive Jet Production in Polarized p+p Collisions at 200 GeV
We report measurements of the longitudinal double spin asymmetry for inclusive jet production using polarized p+p collisions at √ s = 200 GeV at RHIC. Results from the 2005 and 2006 runs are presented. These results set substantial new constraints on the polarized gluon distribution in the proton over the kinematic range 0.02 < x < 0.3, when compared to next-to-leading order global analyses of ...
