Perturbative gravitational wave predictions for the real-scalar extended Standard Model

Abstract We perform a state-of-the-art study of the cosmological phase transitions of the real-scalar extended Standard Model. We carry out a broad scan of the parameter space of this model at next-to-next-to-leading order in powers of couplings. We use effective field theory to account for the nece...
