我们推导出解析约束的非线性鬼免费有效理论的大规模自旋2粒子称为伪线性大规模引力，并在一个广义理论的大规模自旋1粒子，这两个提供简单的IR伽利略理论的完成。对于伪线性大质量引力，我们发现与de Rham、Gabadadze和Tolley大质量引力不同，不存在满足解析性约束的参数空间窗口。对于大量的矢量减少到伽利略在解耦限制，我们发现，没有两个衍生行动是兼容的积极性，但更高的衍生行动可以兼容。
We derive analyticity constraints on a nonlinear ghost-free effective theory of a massive spin-2 particle known as pseudolinear massive gravity, and on a generalized theory of a massive spin-1 particle, both of which provide simple IR completions of Galileon theories. For pseudolinear massive gravity we find that, unlike de Rham, Gabadadze, and Tolley massive gravity, there is no window of parameter space which satisfies the analyticity constraints. For massive vectors which reduce to Galileons in the decoupling limit, we find that no two-derivative actions are compatible with positivity but that higher derivative actions can be made compatible.
