Simon Badger, John M. Campbell, R. Keith Ellis, Ciaran Williams

摘要:

我们计算了希格斯玻色子、夸克-反夸克对和负螺旋度胶子对的单圈振幅,即在次最大螺旋度破坏(NMHV)情况下,A(H,qbar-,q+,g-,g-).计算是使用一个有效的拉格朗日量,这是有效的限制非常大的顶夸克质量。作为本文的结果,所有的振幅为希格斯玻色子玻色子过渡到4个部分子现在是已知的分析在一个循环的顺序。

英文摘要:

We compute the one-loop amplitude for a Higgs boson, a quark-antiquark pair and a pair of gluons of negative helicity, i.e. for the next-to-maximally helicity violating (NMHV) case, A(H, qbar-, q+, g-, g-). The calculation is performed using an effective Lagrangian which is valid in the limit of very large top quark mass. As a result of this paper all amplitudes for the transition of a Higgs boson into 4 partons are now known analytically at one-loop order.
