Kalb-Ramond field and gravitational parity violation

Abstract

Gravitational wave physics can probe theories that extend beyond general relativity. Motivated by recent attention on the Kalb-Ramond field as a dark matter candidate, in this work, we study a parity violating dimension four operator which couples the dual Riemann curvature to the 2-form field. After mapping the equations of motion for the right- and left-handed gravitational wave amplitudes to the novel parametrization recently presented in Jenks et al. [Phys. Rev. D 108, 044023 (2023)], we discuss various constraints on the model parameters in light of the coincident electromagnetic/gravitational wave signal of GW170817 and the GWTC-3 dataset.
