Gravitational waves from Pati-Salam dynamics

Abstract

We show that it is possible to use gravitational wave detectors to observe the occurrence of a first order phase transition in Pati-Salam extensions of the Standard Model. We show that the peak frequency of the expected gravitational wave signals ranges within 0.1--10 Hz. We find amusing that the next generation of gravity waves detectors are able to explore time-honored extensions of the Standard Model occurring at energy scales inaccessible by present and future particle physics accelerators.
