Abstract (english)
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the longitudinal double spin asymmetries, A_LL, for charged pions at midrapidity (|η| < 0.35) in longitudinally polarized p + p collisions at √s = 510 GeV. These measurements are sensitive to the gluon spin contribution to the total spin of the proton in the parton momentum fraction x range between 0.04 and 0.09. One can infer the sign of the gluon polarization from the ordering of pion asymmetries with charge alone.... More The asymmetries are found to be consistent with global quantum-chromodynamics fits of deep-inelastic scattering and data at √s = 200 GeV, which show a nonzero positive contribution of gluon spin to the proton spin.
