DOI: 10.1007/jhep01(2020)131
Abstract: We consider the effective field theory of multiple interacting massive spin-2 fields. We focus on the case where the interactions are chosen so that the cutoff is the highest possible, and highlight two distinct classes… read more here.

Abstract: A bstractWe apply the recently developed positivity bounds for particles with spin, applied away from the forward limit, to the low energy effective theories of massive spin-1 and spin-2 theories. For spin-1 theories, we consider… read more here.

DOI: 10.1007/jhep04(2025)014
Abstract: We use on-shell methods to compute all three-point interactions of massive spin-3/2 particles involving a graviton and particles of spin ≤ 1. By employing the massive spinor-helicity formalism we identify the interactions which have a… read more here.

DOI: 10.1088/1475-7516/2018/07/012
Abstract: We present the consistent theory of a free massive spin-2 field with 5 degrees of freedom propagating in spacetimes with an arbitrary geometry. We obtain this theory via linearizing the equations of the ghost-free massive… read more here.

DOI: 10.3390/sym11010036
Abstract: Fields of spin s ≥ 1 / 2 satisfying wave equations in a curved space obey the Huygens principle under certain conditions clarified by a known theorem. Here, this theorem is generalized to spin zero… read more here.
