Fermion masses and proton decay in string-inspired SU(4)*SU(2)^2*U(1)_X
Thomas Dent, George Leontaris, John Rizos
We present a supersymmetric model of fermion masses with SU(4)*SU(2)^2*U(1)_X gauge group with matter in fundamental and antisymmetric tensor representations only. The up, down, ch…

Leptogenesis through direct inflaton decay to light particles
Thomas Dent, George Lazarides, Roberto Ruiz de Austri
We present a scenario of nonthermal leptogenesis following supersymmetric hybrid inflation, in the case where inflaton decay to both heavy right handed neutrino and SU(2)_L triplet…
