Title: Measurement of parity-violating spin asymmetries in $W^{\pm}$ production at midrapidity in longitudinally polarized $p + p$ collisions

Abstract

In this study, we present midrapidity measurements from the PHENIX experiment of large parity-violating single-spin asymmetries of high transverse momentum electrons and positrons from W^±/Z decays, produced in longitudinally polarized p + p collisions at center of mass energies of √s = 500 and 510 GeV. These asymmetries allow direct access to the antiquark polarized parton distribution functions due to the parity-violating nature of the W-boson coupling to quarks and antiquarks. The results presented are based on data collected in 2011, 2012, and 2013 with an integrated luminosity of 240 pb^–1, which exceeds previous PHENIX published results by a factor of more than 27. These high Q² data probe the parton structure of the proton at W mass scale and provide an important addition to our understanding of the antiquark parton helicity distribution functions at an intermediate Bjorken x value of roughly M_W/ √s = 0.16.

We report the double-helicity asymmetry, AJ=ψ LL , in inclusive J=ψ production at forward rapidity as a function of transverse momentum pT and rapidity jyj. The data analyzed were taken during ffiffiffis p ¼ 510 GeV longitudinally polarized p þ p collisions at the Relativistic Heavy Ion Collider in the 2013 run using the PHENIX detector. At this collision energy, J=ψ particles are predominantly produced through gluon-gluon scatterings, thus AJ=ψ LL is sensitive to the gluon polarization inside the proton.
