Lepton Number Violation at the LHC in Radiative Neutrino Mass Models with Leptoquarks
K. S. Babu, Rahool Kumar Barman, Dorival Gonçalves
We investigate the prospects for observing lepton number violation (LNV) by two units, , at the LHC within the leptoquark variant of the Zee Model, where Majorana neutrin…
Universal Seesaw Pati-Salam Model with P for Strong CP
K. S. Babu, Sumit Biswas
We develop a universal seesaw version of the Pati-Salam model wherein quarks and leptons of each family are unified into common multiplets transforming as $\{ψ_L(2,1,4)+ ψ_R(1,2,4)…
Universal Seesaw Leptogenesis
K. S. Babu, Maximilian Berbig, Srubabati Goswami +1
We study the implications for leptogenesis in a class of left-right symmetric model, where all fermion masses are induced through the Universal Seesaw mechanism. Unlike conventiona…
TeV Scale Quark-Lepton Unification
K. S. Babu, Sumit Biswas, Shaikh Saad
We propose a quark-lepton symmetric Pati-Salam (PS) model based on the gauge group with an -inspired particle spectrum which naturally…
One Phase to Rule Them All: Spontaneous CP Violation and Leptogenesis in SO(10)
K. S. Babu, Chee Sheng Fong, Shaikh Saad
We present a renormalizable grand unified theory with a minimal Yukawa sector consisting of a , a real and a real , where violation has a spontan…
Ultraviolet Completion of a Two-loop Neutrino Mass Model
K. S. Babu, Shaikh Saad
The Zee-Babu model is an economical framework for neutrino mass generation as two-loop quantum corrections. In this work, we present a UV completion of this model by embedding it i…
Dirac Leptogenesis in Left-Right Symmetric Models
K. S. Babu, Ajay Kaladharan
Left-right symmetric models which employ a generalized seesaw mechanism to generate quark and charged lepton masses are known to solve the strong CP problem via parity symmetry, wi…
Leptogenesis in SO(10) with Minimal Yukawa sector
K. S. Babu, Pasquale Di Bari, Chee Sheng Fong +1
In prior studies, a very minimal Yukawa sector within the Grand Unified Theory framework has been identified, comprising of Higgs fields belonging to a real , a real…
