Generalized 331 models
Pritibhajan Byakti, Palash B. Pal
We examine different ways in which the standard model can be embedded into the gauge group. We show that there exist famili…
Supersymmetric gauged U(1) model for neutrinos and the muon anomaly
Heerak Banerjee, Pritibhajan Byakti, Sourov Roy
The gauged model can provide for additional contributions to the muon anomalous magnetic moment by means of a loop involving the gauge boson. However,…
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…
A closer look at the and anomalies
Debjyoti Bardhan, Pritibhajan Byakti, Diptimoy Ghosh
The measurement of (), the ratio of the branching fraction of to that of $\overline{B} \to D l \barν_l (…
Higgs mass from neutrino-messenger mixing
Pritibhajan Byakti, Charanjit K Khosa, V. S. Mummidi +1
The discovery of the Higgs particle at 125 GeV has put strong constraints on minimal messenger models of gauge mediation, pushing the stop masses into the multi-TeV regime. Extensi…
The 750 GeV diphoton resonance as an sgoldstino: a reappraisal
Debjyoti Bardhan, Pritibhajan Byakti, Diptimoy Ghosh +1
Among the various explanations of the possible 750 GeV diphoton resonance, the possibility of it being an sgoldstino is an attractive one, as it is related to the spontaneous break…
Coxeter groups and the PMNS matrix
Pritibhajan Byakti, Palash B. Pal
We discuss the symmetries of the Lagrangian of the leptonic sector. We consider the case when this symmetry group is a Coxeter group. The number of elements of the PMNS matrix pred…
Alternative search strategies for a BSM resonance fitting ATLAS diboson excess
Biplob Bhattacherjee, Pritibhajan Byakti, Charanjit K. Khosa +2
We study an s-channel resonance as a viable candidate to fit the diboson excess reported by ATLAS. We compute the contribution of the TeV resonance to semileptonic…
Number of fermion generations from a novel Grand Unified model
Pritibhajan Byakti, David Emmanuel-Costa, Arindam Mazumdar +1
Electroweak interactions based on a gauge group , coupled to the QCD gauge group , can predict the number of generations to be multiples of…
Burgeoning the Higgs mass to 125 GeV through messenger-matter interactions in GMSB models
Pritibhajan Byakti, Tirtha Sankar Ray
A 125 GeV Higgs renders the simpler GMSB models unnatural, essentially pushing the soft spectrum beyond the LHC reach. A direct coupling of the matter and messenger fields, that fa…
Magic Messengers in Gauge Mediation and signal for 125 GeV boosted Higgs boson
Pritibhajan Byakti, Diptimoy Ghosh
We consider a renormalizable messenger sector with magic messenger fields instead of usual SU(5) complete multiplets. We derive the soft supersymmetry breaking terms and show that…
Supersymmetry Breaking: constraint on U(1) R-charge
Pritibhajan Byakti
Holomorphy of the superpotential promotes any continuous symmetry group G to a complexified symmetry group G_C of the superpotential. For U(1) symmetry this means that the superpot…
Discrete R-symmetries and F-term Supersymmetry Breaking
Pritibhajan Byakti
We have shown that in a large number of generic and renormalizable Wess-Zumino models existence of a R-symmetry is sufficient to break supersymmetry spontaneously. This impli…
Theta-parity in supersymmetry
Pritibhajan Byakti, Palash B Pal
We consider invariance of the action of N=1 supersymmetric theories under the change of sign of the fermionic co-ordinate in superspace. We show that the R-parity can be realized a…
