Small-instanton effects in an atlas of KSVZ axion models
Ning Chen, Saurabh K. Shukla
We investigate small-instanton contributions to the axion potential across a range of KSVZ models containing vector-like quarks~(VQs), using naive dimensional analysis. We consider…
Scalar-induced Neutrinoless Double Beta Decay in
P. S. Bhupal Dev, Srubabati Goswami, Debashis Pachhar +1
We discuss the role of heavy scalar fields in mediating neutrinoless double beta decay within the Grand Unified Theory framework, extended suitably to include n…
Constraining scalars of through proton decays in non-renormalisable models
Saurabh K. Shukla
Non-renormalisable versions of \, based on irreducible representations with lesser degrees of freedom, are free of running into the catastrophe of non-perturbativity of sta…
Revisiting Yukawa Sectors Through Quantum Corrections
Saurabh K. Shukla
This article revisits the validity of tree-level statements regarding the Yukawa sector of various minimal-renormalisable \(SU(5)\) frameworks at the loop level. It is well-known t…
