论文摘要
我们构建了一类无限的新紫外线完整的四颗粒散射幅度，这些散射幅度降低了以低能量下降到爱因斯坦的重力，在高能下消失，是meromormorphic的，并且表现出三重生产结构$ {\ cal a}}（s）{\ cal a}（\ cal a}（t）（t）光谱不变地以每个质量极的无限塔的形式表现出积累点，它们的残留物可以在洛伦兹组不可减至表示的树级交换上积极扩展。
We construct an infinite class of new ultraviolet-complete four-graviton scattering amplitudes that reduce to Einstein gravity at low energies, vanish at high energies, are meromorphic, and exhibit a triple-product structure ${\cal A}(s){\cal A}(t){\cal A}(u)$. The spectrum invariantly exhibits accumulation points in the form of infinite towers of states on each mass pole, whose residue can be positively expanded on tree-level exchanges of irreducible representations of the Lorentz group.
