论文摘要
我们确定了三环形式因子在QCD中使用单个质量夸克的木融合中产生脱壳希格斯玻色子的幅度。结果是通过用于发生的主积分的微分方程系统的数值解决方案获得的。该解决方案还用于确定外形要素的高能和阈值膨胀。我们的发现可用于评估Higgs Boson Hadrododulation cross截面的Top-Quark和B-Quark循环生成的虚拟校正,并在近代临时到领先顺序。
We determine the three-loop form factor parameterising the amplitude for the production of an off-shell Higgs boson in gluon fusion in QCD with a single massive quark. The result is obtained via a numerical solution of a system of differential equation for the occurring master integrals. The solution is also used to determine the high-energy and threshold expansions of the form factor. Our findings may be used for the evaluation of virtual corrections generated by top-quark and b-quark loops in Higgs boson hadroproduction cross sections at next-to-next-to-leading order.
