| 英文摘要 | We study the scattering of a single parton state with a multiparton state to derive the complete results of perturbative coefficient functions at leading order, which appear in the collinear factorization for single transverse-spin asymmetry (SSA) in Drell-Yan processes with a transversely polarized hadron in the initial state. We find that the factorization formula of SSA contains hard-pole, soft-quark-pole, and soft-gluon-pole contributions. It is interesting to note that the leading-order perturbative coefficient functions of soft-quark-pole and soft-gluon-pole contributions are extracted from parton-scattering amplitudes at one-loop, while the functions of hard-pole contributions are extracted from the tree-level amplitudes at tree-level. Our method to derive the factorization of SSA is different than the existing one in literature. A comparison of our results with those obtained by other methods is made here. |
