论文摘要
我们通过分析将两环横川校正计算为Higgs Boson对的产生,以高能量极限。这种更正是通过在虚拟顶部夸克线之间交换希格斯玻色子来生成的。我们提出了两种方法,以获得大规模两环积分的扩展,并表明,对于高于150 GEV的希格斯玻色子的横向动量,获得了精确的结果。我们详细讨论所有140个主积分的计算,并呈现分析结果。
We analytically compute two-loop Yukawa corrections to Higgs boson pair production in the high-energy limit. Such corrections are generated by an exchange of a Higgs boson between the virtual top quark lines. We propose two approaches to obtain expansions of the massive two-loop box integrals and show that precise results are obtained for transverse momenta of the Higgs bosons above about 150 GeV. We discuss in detail the computation of all 140 master integrals and present analytic results.
