1. B-meson charged current anomalies: The post-Moriond 2019 status / Bardhan, Debjyoti ; Ghosh, Diptimoy
In this paper, we discuss the impact of the recent Belle result on the various theoretical explanations of the RD and RD* anomalies. [...]

2. 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. [...]

3. 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 non-universal new physics in semi-leptonic B meson decays. [...]

4. A closer look at the R D and R D* anomalies / Bardhan, Debjyoti ; Byakti, Pritibhajan ; Ghosh, Diptimoy
The measurement of R D ( R D * ), the ratio of the branching fraction of B ¯ → D τ ν ¯ τ B ¯ → D ∗ τ ν ¯ τ $$ \overline{B}\to D\tau {\overline{\nu}}_{\tau}\left(\overline{B}\to {D}^{\ast}\tau {\overline{\nu}}_{\tau}\right) $$ to that of B ¯ → D l ν ¯ l B ¯ → D ∗ l ν ¯ l $$ \overline{B}\to Dl{\overline{\nu}}_l\left(\overline{B}\to {D}^{\ast }l{\overline{\nu}}_l\right) $$ , shows 1 .

5. 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. [...]
