Nonperturbative-transverse-momentum effects and evolution in dihadron and direct photon-hadron angular correlations in p+p collisions at √s = 510 GeV

Popis výsledku v původním jazyce

Dihadron and isolated direct photon-hadron angular correlations are measured in p+p collisions at s=510  GeV. Correlations of charged hadrons of 0.7<pT<10  GeV/c with π0 mesons of 4<pT<15  GeV/c or isolated direct photons of 7<pT<15  GeV/c are used to study nonperturbative effects generated by initial-state partonic transverse momentum and final-state transverse momentum from fragmentation. The nonperturbative behavior is characterized by measuring the out-of-plane transverse momentum component pout perpendicular to the axis of the trigger particle, which is the high-pT direct photon or π0. Nonperturbative evolution effects are extracted from Gaussian fits to the away-side inclusive-charged-hadron yields for different trigger-particle transverse momenta (pTtrig).n
