Confronting SO(10) GUTs with proton decay and gravitational waves

King, Stephen F.; Pascoli, Silvia; Zhou, Ye-Ling +1 more

Grand Unified Theories (GUT) predict proton decay as well as the formation of cosmic strings which can generate gravitational waves. We determine which non-supersymmetric SO(10) breaking chains provide gauge unification in addition to a gravitational signal from cosmic strings. We calculate the GUT and intermediate scales for these SO(10) breaking…
