本文计算了在大型强子对撞机（LHC）上单喷流作用下玻色子产生截面的贡献，并研究了它们与LHC物理的唯象关联。强子喷流的产生需要精确的预测来控制一个背景，这个背景极大地影响了希格斯玻色子性质的测量和LHC新物理的研究。同时，它可以使夸克部分子分布函数的第一次精确测量。在这种背景下，夸克质量效应变得相关，需要仔细研究，无论是在硬过程的水平上，还是在初态和终态部分子演化的水平上。这是本文的目的是探讨这些问题的框架内的一个大规模的五味计划，并评估是否需要列入两个电弱修正，除了QCD修正，和夸克质量效应的预测总截面和微分截面的强子喷流生产。
We compute theandcontributions to the production cross section of aboson with onejet at the Large Hadron Collider (LHC) and study their phenomenological relevance for LHC physics. The accurate prediction of hadronic-jet production is needed to control a background that greatly affects both the measurement of Higgs-boson properties and the searches of new physics at the LHC. At the same time it could enable the first precise measurement of the-quark parton distribution function. In this context-quark mass effects become relevant and need to be studied with care, both at the level of the hard process and at the level of the initial- and final-state parton evolution. It is the aim of this paper to explore some of these issues in the framework of a massive five-flavor scheme and to assess the need for the inclusion of both electroweak corrections, in addition to QCD corrections, and-quark mass effects in the prediction of total and differential cross sections for hadronic-jet production.
