摘要： 我们考虑最近ATLAS和CMS观测到的750 GeV质量共振的最小有效相互作用。 假设一个新的标量和规范不变的有效相互作用会导致与渐近规范玻色子态的非平凡两粒子散射振幅。 纵向极化的$W\pm$和$Z$玻色子通过五维有效算符相互作用，对有效模型的有效性提供了严格的限制。 ATLAS发现的大宽度暗示在共振以下约500 GeV处有一个上限，使这种情形变得不太可能。 对于主要通过胶子融合产生的情况，我们得到一个上限为$\sim 1.3$TeV，同时还给出了对底层矢量样费米子质量的强烈限制。 显示英文摘要

摘要： We consider minimal effective interactions of the 750 GeV mass resonance observed recently by ATLAS and CMS. Assuming a new scalar and gauge invariant effective interactions leads to non-trivial two particle scattering amplitudes with asymptotic gauge boson states. The longitudinally polarized $W\pm$ and $Z$ bosons interacting via dimension-five effective operators provide stringent constraints on the validity of the effective model. The large width found by ATLAS implying a bound of approximately 500 GeV already below the resonance, turns this scenario unlikely. For production mainly in gluon fusion we get an upper bound of $\sim 1.3$ TeV and strong limits on the masses of the underlying vector-like fermions are given.
