High Energy Theory Lunchtime Seminar

Friday, December 7th 2018
Speaker: K. S. Babu (Oklahoma State U.)
Subject: Fermion masses, proton decay and the strong CP problem in SUSY SO(10)

In this talk, I shall present new results on fermion masses and mixings and proton decay in the context of renormalizable SUSY SO(10) models. Difficulties with the minimal model are avoided by enlarging the symmetry breaking sector with a 54. Consistent fermion mass spectrum is obtained, including the neutrino sector. A mini-split SUSY spectrum is suggested by proton decay constraints, which is compatible with pure gravity mediation. A successful implementation of the Peccei-Quinn symmetry will be presented, in which case the model becomes compatible with proton lifetime with TeV scalars.
