Longitudinal double-spin asymmetry for inclusive jet and dijet production in polarized proton collisions at √s = 510 GeV
Original language description
We report measurements of the longitudinal double-spin asymmetry, A(LL), for inclusive jet and dijet production in polarized proton-proton collisions at midrapidity and center-of-mass energy root s = 510 GeV, using the high luminosity data sample collected by the STAR experiment in 2013. These measurements complement and improve the precision of previous STAR measurements at the same center-of-mass energy that probe the polarized gluon distribution function at partonic momentum fraction 0.015 less than or similar to x less than or similar to 0.25. The dijet asymmetries are separated into four jet-pair topologies, which provide further constraints on the x dependence of the polarized gluon distribution function. These measurements are in agreement with previous STAR measurements and with predictions from current next-to-leading-order global analyses. They provide more precise data at low dijet invariant mass that will better constrain the shape of the polarized gluon distribution function of the proton.
