Description
We investigate the transverse single-spin asymmetry (TSSA) for the very forward neutral pion production by employing the triple-Regge exchanges. The TSSA is ratio of spin-dependent and spin-averaged differential cross section. In the RHICf energy($\sqrt{s}=510\,\mathrm{GeV}$), the inclusive $p+p^\uparrow\to\pi^0+X$ process will be diffractive, so that $d\sigma$ can be expressed in terms of the triple-Regge exchanges. Our numerical results are in a remarkable agreement with RHICf data. It indicates that $A_N$ is of diffractive nature in the low $p_T$ region.
