We investigate primordial gravitational waves (GWs) to test flavor violation and baryogenesis, where a long-lived flavon field decays, generating baryon asymmetry and causing an intermediate matter domination epoch that suppresses GWs [1]. Detectable by DECIGO, BBO, LISA, and ET, this suppression informs parameter constraints on the flavon mass and decay width.

摘要

We investigate primordial gravitational waves (GWs) to test flavor violation and baryogenesis, where a long-lived flavon field decays, generating baryon asymmetry and causing an intermediate matter domination epoch that suppresses GWs [1]. Detectable by DECIGO, BBO, LISA, and ET, this suppression informs parameter constraints on the flavon mass and decay width.
