High-energy properties of the graviton scattering in quadratic gravity
Abstract We obtain the matter-graviton scattering amplitude in the gravitational theory of quadratic curvature, which has R μν 2 $$ {R}_{\mu \nu}^2 $$ term in the action. Unitarity bound is not satisfied because of the existence of negative norm states, while an analog of unitarity bound for S-matri...
