Bootstrapping the chiral-gravitational anomaly

Abstract We analyze causality and unitarity constraints in graviton scattering amplitudes, aiming to establish new bounds on theories with U(1)-gravitational anomalies, such as axion models or strongly-coupled gauge theories. For this purpose, we show the necessity of coupling these theories to grav...
