Abstract

It is well known that effective field theories exhibit unitarity violation at high energies signaling the breakdown of the expansion. This project aims to study the partial-wave unitarity constraints on the Wilson coefficients of effective lagrangians parametrizing the interaction of spin-2 candidates for dark matter. (AU)
