Involution symmetries and the PMNS matrix
Palash B. Pal, Pritibhajan Byakti
Lam suggested that the PMNS matrix (or at least some of its elements) can be predicted by embedding the residual symmetry of the leptonic mass terms into a bigger symmetry. We anal…
Note on gauge and gravitational anomalies of discrete symmetries
Pritibhajan Byakti, Diptimoy Ghosh, Tarun Sharma
In this note, we discuss the consistency conditions which a discrete symmetry should satisfy in order that it is not violated by gauge and gravitational instantons. As exampl…
Role of Tensor operators in and
Debjyoti Bardhan, Pritibhajan Byakti, Diptimoy Ghosh
The recent LHCb measurement of in two bins, when combined with the earlier measurement of , strongly suggests lepton flavour non-universal new physics in semi-…
Unification with Vector-like fermions and signals at LHC
Biplob Bhattacherjee, Pritibhajan Byakti, Ashwani Kushwaha +1
We look for minimal extensions of Standard Model with vector like fermions leading to precision unification of gauge couplings. Constraints from proton decay, Higgs stability and p…
