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...

متن کاملGluon Contributions to Parity-Violating Asymmetries in Polarized Proton-Proton Scattering
We report on a calculation of one-loop weak corrections to polarized quark-gluon scattering and the corresponding crossed channels. Such contributions are suppressed formally by one power of αs relative to W− or Z−mediated quark-quark scattering, but would enable the spin asymmetry of the gluon distribution to contribute to parity-violating asymmetries that will soon be investigated in polarize...
متن کاملRecent 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...
