摘要:

考虑了带电和中性电流Drell-Yan过程的非线性QCD修正及其在计算机系统SANC中的实现。在部分子水平上,我们考虑了夸克-反夸克和夸克-胶子散射通道。在大量的情况下,共线奇点的减法进行了比较,在MS-酒吧计划。给出了SANC在强子水平上的结果。与MCFM包的结果比较。

英文摘要:

NLO QCD corrections to charged and neutral current Drell-Yan processes and their implementation in the computer system SANC are considered. On the partonic level both quark-antiquark and quark-gluon scattering channels are taken into account. Subtractions of the collinear singularities in the massive case are compared with ones in the MS-bar scheme. Results of SANC on the hadronic level are presented. Comparison with results of the MCFM package is shown.
