QCD中的跨晶体极化Drell-Yan过程和胶子软恢复

Transversely Polarized Drell-Yan Process and Soft Gluon Resummation in QCD

Hiroyuki Kawamura, Jiro Kodaira, Kazuhiro Tanaka

摘要:

利用QCD中的因式分解定理计算了双轻子在横向极化Drell-Yan过程中的横动量$Q_T$谱。通过在小的$Q_T$区域内对多个软胶子辐射进行各阶的数值计算,我们考虑了相空间边缘区域的普适修正。

英文摘要:

We calculate the transverse-momentum $Q_T$ spectrum of the dilepton in the transversely polarized Drell-Yan process on the basis of the factorization theorem in QCD. We take into account universal logarithmically enhanced corrections in edge region of phase space by resumming multiple soft-gluon emissions to all orders in the small $Q_T$ region.
