High Scale Type-II Seesaw, Dominant Double Beta Decay within Cosmological Bound and LFV Decays in SU(‎5) by M. K. Parida, Rajesh Satpathy

“…Very recently novel implementation of type-II seesaw mechanism for neutrino mass has been proposed in SU(5) grand unified theory with a number of desirable new physical phenomena beyond the standard model. …”

Axion dark matter, proton decay and unification by Pavel Fileviez Pérez, Clara Murgui, Alexis D. Plascencia

“…Abstract We discuss the possibility to predict the QCD axion mass in the context of grand unified theories. We investigate the implementation of the DFSZ mechanism in the context of renormalizable SU(5) theories. …”

T-model Higgs inflation and metastable cosmic strings by C. Pallis

“…The decay of the produced CSs interprets the recent observations from PTA experiments on the stochastic background of gravitational waves with values of the superpotential coupling constants close to 10−6 − 10−8 and symmetry-breaking scales a little lower than the SUSY grand unified theory scale. A solution to the μ problem of the MSSM is also accommodated provided that μ is two to three orders of magnitude lower than the gravitino mass. …”
