On the flat transverse momentum dependence of the single-spin asymmetry in inclusive neutral pion production

We discuss recent experimental results from RHIC where the flat transverse momentum dependence of a single-spin asymmetry has been found in inclusive production of neutral pions. This dependence takes place in a wide region of the transverse momenta up to p_T=10 GeV/c. We emphasize that such dependence has been predicted... Show more
