The inclusive jet ALL measurement is sensitive to the gluon helicity distribution down to a gluon momentum fraction of x?0.015, while the dijet measurements, separated into four jet-pair topologies, provide constraints on the x dependence of the gluon polarization. Both results are consistent with previous measurements made at √s=200??GeV in the overlapping kinematic region, x>0.05, and show good agreement with predictions from recent next-to-leading order global analyses.}, title = {Longitudinal double-spin asymmetry for inclusive jet and dijet production in pp collisions at √s=510??GeV}, volume = {100}, year = {2019}, yomi = {エスミ, シンイチ} }
