Graviton mass constraint from CMB

Published 12 Jan 2017 in gr-qc | (1701.03316v1)

Abstract: The effect of primordial massive gravitational waves on the BB-mode correlation angular power spectrum of CMB is studied for several inflation models. The angular power spectrum with the BICEP2/Keck Array and Planck joint data suggests further constraint on the lower and upper bounds on the mass of primordial gravitons
