我们给出了构造希格斯玻色子和任意数量的部子的微扰振幅的MHV规则。我们给出了包含一个希格斯和三个负螺旋度部件以及任意数量的正螺旋度部件的振幅的显式表达式--NMHV振幅。我们还给出了包含希格斯、夸克和胶子的MHV规则的递归公式。该递推关系对所有非MHV幅值均有效。一般结果与所有可用的Higgs+n-Parton振幅在数值上是一致的,并且在某些情况下提供了相当短的表达式。
We present MHV-rules for constructing perturbative amplitudes for a Higgs boson and an arbitrary number of partons. We give explicit expressions for amplitudes involving a Higgs and three negative helicity partons and any number of positive helicity partons - the NMHV amplitudes. We also present a recursive formulation of MHV rules that incorporates the Higgs, quarks and gluons. The recursion relations are valid for all non-MHV amplitudes. The general results agree numerically with all of the available Higgs + n-parton amplitudes and in some cases provide considerably shorter expressions.
