摘要:

本文给出了初始粒子纵向极化情形下中性流Drell-Yan过程$p p \to \ell^+\ell^- X$的完整单圈电弱修正。纵向极化质子的截面使我们能够从单自旋和双自旋不对称性中估计极化夸克分布的不同组合。利用MC生成器ReneSANCe,在强子-强子质心系中,作为矢量玻色子快度和轻子赝快度的函数,对电弱次阶修正对不对称性的数值影响进行了深入研究。

英文摘要:

Complete one-loop electroweak corrections to neutral current Drell-Yan process $p p \to \ell^+\ell^- X$ are presented for the case of longitudinal polarization of initial particles. Cross sections for longitudinally polarized protons allow us to estimate different combinations of polarized quark distributions from single- and double-spin asymmetries. Numerical impact of electroweak next-order corrections to asymmetries as function of the vector boson rapidity and lepton pseudorapidities in the hadron-hadron centre-of-mass frame using the MC generator ReneSANCe is thoroughly studied.
