Bottom-tau unification by neutrinos in a nonsupersymmetric SU(5) model

High Energy Physics - Phenomenology 2025-11-26 v2

Abstract

We show that Yukawa couplings of bottom quarks and tau leptons can be unified in a non-supersymmetric SU(5) model. We introduce an arbitrary number of right-handed neutrinos. Their masses and Yukawa couplings that satisfy the unification condition by renormalization group evolution are shown. In the case that the grand unification scale is 1015.510^{15.5}GeV and three right-handed neutrinos have the same mass, the upper bound on their mass is 1014.1\sim 10^{14.1}GeV.
