Measurements of the Z0/γ⁎ cross section and transverse single spin asymmetry in 510 GeV p + p collisions
Original language description
The differential cross section for Z(0) production, measured as a function of the boson's transverse momentum (p(T)), provides important constraints on the evolution of the transverse momentum dependent parton distribution functions (TMDs). The transverse single spin asymmetry (TSSA) of the Z(0) is sensitive to one of the polarized TMDs, the Sivers function, which is predicted to have the opposite sign in p + p -> W/Z + X from that which enters in semi-inclusive deep inelastic scattering. In this Letter, the STAR Collaboration reports the first measurement of the Z(0)/gamma* differential cross section as a function of its p(T) in p + p collisions at a center-of-mass energy of 510 GeV, together with the Z(0)/gamma* total cross section. We also report the measurement of Z(0)/gamma* TSSA in transversely polarized p + p collisions at 510 GeV.
