论文摘要
最近,RHICF协作测量了在$ \ sqrt {s} = 510 $ GEV中,在极化的$ p+p $碰撞中非常向前中性亲的横向单旋旋转不对称,在大型伪the($η\ gtrsim 6 $)上产生。数据显示了纵向动量分数$ x_f $和横向动量$ p_t $ at $ p_t <1 \,\ mathrm {gev}/c $的大型不对称。我们首次使用Baryonic Triple Regge交换,描述了完整的RHICF数据,并表明低$ P_T $的中性触发产生可以解释为衍射率。
Recently, the RHICf Collaboration measured the transverse single-spin asymmetries of the very forward neutral pion in polarized $p+p$ collisions at $\sqrt{s}=510$ GeV, produced at large pseudorapidity ($η\gtrsim 6$). The data show large asymmetries both in longitudinal momentum fraction $x_F$ and transverse momentum $p_T$ at $p_T<1\,\mathrm{GeV}/c$. Employing baryonic triple Regge exchanges, we describe the complete RHICf data for the first time and show that the neutral pion production at low $p_T$ can be interpreted as a diffractive one.
