Abstract:
Transverse single spin asymmetry, A N , of very forward π 0 production from polarized p + p collisions provides new information toward an understanding of its production mechanism. A N of forward π 0 in the pseudorapidity region of 3 〈 η 〈 4 has been described by the partonic structure of the proton in the perturbative QCD framework. However, recent data indicates a potential contribution from not only partonic but also diffractive interactions. In order to provide a new insight on the origin of the A N , we measured the very forward π 0 production in the pseudorapidity region of 6 〈 η from √s = 510 GeV polarized p + p collisions at RHIC in 2017. We report our measurement of the very forward π 0 over the transverse momentum range of 0 〈 p T 〈 1 GeV/c and the preliminary result.
