摘要:

我们给出了在Tevatron和LHC上的高质量电子-μ子对产生的截面的理论预言,直到QCD NLO,只考虑第三代sneutrino的主要贡献。研究了重正化标度和因子化标度对总截面的依赖关系,以及部分子分布函数的不确定性对K因子的影响.通过在首对数的$α_s$中考虑软胶子重算效应,给出了末态$eμ$对的横动量分布.

英文摘要:

We present the theoretical predictions up to QCD NLO for the cross section of high-mass electron-muon pair production at the Tevatron and the LHC, considering only the dominant contributions from the third-generation sneutrino. The dependence of the renormalization and factorization scales on the total cross section, and the effects on the K-factor due to the uncertainty of parton distribution function(PDF) have been carefully investigated. By considering soft-gluon resummation effects to all order in $α_s$ of leading logarithm, we present the transverse momentum distributions of the final $eμ$ pair.
