Recent results and prospects on exploring the helicity structure of the proton at RHIC in high-energy polarized proton-proton collisions

The STAR Collaboration is pursuing measurements to help understand the origin of the proton spin. The gluon polarization is accesible via measurements of the longitudinal double-spin asymmetry, ALL , for inclusive charged and neutral pions and inclusive jet production. A recent global analysis of polarized DIS data and RHIC spin data disfavors extreme gluon polarization scenarios. The measureme...

Recent results of the STAR high-energy polarized proton-proton program at RHIC at BNL

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...

MC simulation of vector boson production in polarized proton collisions

We present a Monte Carlo (MC) study of W and Z0 production of longitudinally polarized proton collisions at a center of mass (CMS) energy of 500GeV. All results were obtained with the SPHINX MC code. We consider two different types of polarized parton distributions with large and small gluon polarization. Various spin asymmetries are found to be sensitive to the shape of the polarized gluon dis...
