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^{(*…
Dark photon and dark mediated meson decays
Alakabha Datta, A. Hammad, Danny Marfatia +2
We study flavor changing neutral current decays of and mesons in the dark model, with the dark photon/dark mass between 10 MeV and 2 GeV. Although the model pr…
FCNC in Concurrent Dark Photon and Dark Models
Lopamudra Mukherjee
In this work we fit the available binned data of the differential decay distribution of the exclusive and decays to the mass and mi…
Implications for the anomaly in using a new Monte Carlo Event Generator
Bhubanjyoti Bhattacharya, Thomas E. Browder, Quinn Campagna +4
Recent experimental results in physics from Belle, BaBar and LHCb suggest new physics (NP) in the weak charged-current and the neutral-current processes. Here…
A new tool to search for physics beyond the Standard Model in
Bhubanjyoti Bhattacharya, Thomas Browder, Quinn Campagna +4
Recent experimental results in physics from Belle, BaBar and LHCb suggest new physics (NP) in the weak charged-current and the neutral-current processes. Here…
Shedding Flavor on Dark via Freeze-in: Gauged Extensions
Basabendu Barman, Purusottam Ghosh, Anish Ghoshal +1
We consider a singlet fermionic dark matter (DM) in a gauged extension of the Standard Model (SM), with , and derive bounds on the allowed param…
Constraining New Physics with Possible Dark Matter Signatures from a Global CKM Fit
Aritra Biswas, Lopamudra Mukherjee, Soumitra Nandi +1
We constrain the parameters of a representative new physics model with possible dark matter (DM) signature from a global CKM fit analysis. The model has neutral quark current inter…
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…
