We explore the leptonic sector of a recently proposed supersymmetric SO(10) model with supersymmetry breaking in the 3–10 TeV range. A new ingredient in this work is the requirement that the observed baryon asymmetry is explained via non-thermal leptogenesis, which can be realized in a large class o ...

Next-generation experiments, such as the Deep Underground Neutrino Experiment and the European Spallation Source, are set to improve sensitivity to neutron-antineutron oscillation, a direct probe of ∆B = 2 baryon number violation, with particularly significant gains expected at the latter. The disco ...

In light of the recent Particle Data Group (PDG) release, we revisit the running quark and lepton Yukawa couplings, together with the quark mixing parameters, across a range of energy scales. The 2024 PDG determinations of low-energy fermion masses feature significantly smaller uncertainties, result ...

What does third family (t-b-τ) Yukawa unification, a typical prediction from embedding the Standard Model (SM) fermions in 16-plets of a grand unifying SO(10) gauge symmetry, imply for the scale of the supersymmetric (SUSY) partners? Which neutralino dark matter candidate can be realized, and how la ...

The Georgi-Glashow model is the simplest possible attempt at grand unification. However, due to its particle content, the model preserves a global symmetry, where B and L are baryon and lepton numbers, respectively. It thus leaves neutrinos massless just as the Standard Model does. The extensions of ...

We propose a quark-lepton symmetric Pati-Salam (PS) model based on the gauge group SU(2)L × SU(2)R × SU(4)C with an E6-inspired particle spectrum which naturally accommodates a multi-TeV leptoquark gauge boson . A softly broken Z2 symmetry plays a crucial role in realizing this scenario, under which ...

We assess proton decay signatures in the simplest viable $SU(5)$ model with regard to constraints on parameters governing the Standard Model fermion mass spectrum. Experimental signals for all eight two-body proton decay processes result from exchange of two gauge bosons, a single scalar leptoquark, ...
