Anatomy of b → c τ ν anomalies
/ Azatov, Aleksandr ; Bardhan, Debjyoti ; Ghosh, Diptimoy ; Sgarlata, Francesco ; et al
In recent times, one of the strongest hints of Physics Beyond the Standard Model (BSM) has been the anomaly in the ratios R D and R D * $$ {R}_{D^{*}} $$ measured in the charged current decays of B mesons. [...]

Note on gauge and gravitational anomalies of discrete Z N symmetries
/ Byakti, Pritibhajan ; Ghosh, Diptimoy ; Sharma, Tarun
In this note, we discuss the consistency conditions which a discrete Z N symmetry should satisfy in order that it is not violated by gauge and gravitational instantons. [...]

Role of tensor operators in R K and RK⁎
/ Bardhan, Debjyoti ; Byakti, Pritibhajan ; Ghosh, Diptimoy
The recent LHCb measurement of RK⁎ in two q2 bins, when combined with the earlier measurement of RK , strongly suggests lepton flavour nonuniversal new physics in semileptonic B meson decays. [...]

The 750 GeV diphoton resonance as an sgoldstino: a reappraisal
/ Bardhan, Debjyoti ; Byakti, Pritibhajan ; Ghosh, Diptimoy ; Sharma, Tarun
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 breaking of global supersymmetry. [...]
