Transverse single-spin asymmetry of very forward neutral pion
Abstract
We present in this talk a recent work on the transverse single-spin asymmetry of the very forward neutral pion in polarized p+p collisions at √S = 510s=510 GeV. The triple-Regge formalism remarkably well desribes the RHICf data at pT < 1 GeV. We found that the neutral pion production at low pT is interpreted as a diffractive one.
