Two-field cosmological phase transitions and gravitational waves in the singlet Majoron model

Abstract In the singlet Majoron model, we study cosmological phase transitions (PTs) and their resulting gravitational waves (GWs), in the two-field phase space, without freezing any of the field directions. We first calculate the effective potential, at one loop and at finite temperature, of the St...
