标题： Regge growth of isolated massive spin-2 particles and the Swampland

摘要： 我们考虑一个单一的大质量自旋-2粒子并且存在能隙到截止尺度的有效理论。 我们将自旋-2粒子耦合到引力和其他低自旋场，并研究粒子在Regge区域中的散射振幅增长：其中$s$远大于$t$以及有效理论中的任何质量尺度，但仍然远低于理论的截止尺度且因此也远低于任何进一步的大质量自旋-2粒子。 我们在有效理论中包含所有可能算符，具有任意但有限数量的导数。 我们证明在这种理论中散射振幅的增长严格快于$s^2$。 如此快速的增长违背了预期的Regge增长界限。 因此，我们找到了Swampland自旋-2猜想的进一步证据：即具有孤立大质量自旋-2粒子并且耦合到引力的理论属于Swampland。 显示英文摘要

摘要： We consider an effective theory with a single massive spin-2 particle and a gap to the cutoff. We couple the spin-2 particle to gravity, and to other lower-spin fields, and study the growth of scattering amplitudes of the particle in the Regge regime: where $s$ is much larger than $t$ and also any mass scales in the effective theory, but still much lower than the cutoff scale of the theory and therefore any further massive spin-2 particles. We include in the effective theory all possible operators, with an arbitrary, but finite, number of derivatives. We prove that the scattering amplitude grows strictly faster than $s^2$ in any such theory. Such fast growth goes against expected bounds on Regge growth. We therefore find further evidence for the Swampland spin-2 conjecture: that a theory with an isolated massive spin-2 particle, coupled to gravity, is in the Swampland.
