Hint of a new scalar interaction in LHCb data?
Alakabha Datta, Danny Marfatia, Lopamudra Mukherjee
We explain recent LHCb measurements of the lepton universality ratios, $R_{D^{(*)}}^{τ/\ell}\equiv \frac{\mathcal{B}(\bar B \to D^{(*)+} τ^- \barν_τ)} {\mathcal{B}(\bar B \to D^{(*…

Low Scale Gauge Symmetry as an Origin of Dark Matter, Neutrino Mass and Flavour Anomalies
Debasish Borah, Lopamudra Mukherjee, Soumitra Nandi
We study a generic leptophilic extension of the standard model with a light gauge boson. The charge assignments for the leptons are guided by lepton universality…

Correlating the anomalous results in decays with inert Higgs doublet dark matter and muon
Basabendu Barman, Debasish Borah, Lopamudra Mukherjee +1
In this article, we have considered an extension of the inert Higgs doublet model with singlet vector like fermions. Our model is capable of addressing some interesting a…
