标题： Compact multigluonic scattering amplitudes with heavy scalars and fermions

摘要： 结合Berends-Giele递归关系和现场递归关系，我们得到了复杂标量-反标量对和任意数量正螺旋度胶子散射振幅的一个极其紧凑的表达式。 这是从递归关系构造其他螺旋度构型的基本构建块之一。 我们还明确展示了重费米子的所有正螺旋度胶子振幅与标量振幅成正比，从而证实了最近提出的与这两个振幅相关的SUSY类Ward恒等式。 显示英文摘要

摘要： Combining the Berends-Giele and on-shell recursion relations we obtain an extremely compact expression for the scattering amplitude of a complex scalar-antiscalar pair and an arbitrary number of positive helicity gluons. This is one of the basic building blocks for constructing other helicity configurations from recursion relations. We also show explicity that the all positive helicity gluons amplitude for heavy fermions is proportional to the scalar one, confirming in this way the recently advocated SUSY-like Ward identities relating both amplitudes.
