Eikonal Scattering and Asymptotic Superluminality of Massless Higher Spin Fields
Kurt Hinterbichler, Austin Joyce, Rachel A. Rosen
We consider scattering of massless higher-spin particles in the eikonal regime in four dimensions. By demanding the absence of asymptotic superluminality, corresponding to positivi…
Massive and Massless Spin-2 Scattering and Asymptotic Superluminality
James Bonifacio, Kurt Hinterbichler, Austin Joyce +1
We constrain theories of a massive spin-2 particle coupled to a massless spin-2 particle by demanding the absence of a time advance in eikonal scattering. This is an -matrix con…
Massive Spin-2 Scattering and Asymptotic Superluminality
Kurt Hinterbichler, Austin Joyce, Rachel A. Rosen
We place model-independent constraints on theories of massive spin-2 particles by considering the positivity of the phase shift in eikonal scattering. The phase shift is an asympto…
