Primordial gravitational waves from spontaneous Lorentz symmetry breaking
Mohsen Khodadi, Gaetano Lambiase, Leonardo Mastrototaro +1
We study the effect of Spontaneous Lorentz Symmetry Breaking (SLSB) on Primordial Gravitational Waves (PGWs) generated during inflation. The SLSB is induced by a time-like Bumblebe…
