$B \to K ν ν ˉ$ , MiniBooNE and muon $g - 2$ anomalies from a dark sector

Alakabha Datta, Danny Marfatia, Lopamudra Mukherjee

Belle II has reported the first evidence for $B^{+} \to K^{+} ν ν ˉ$ with a branching ratio $2.7 σ$ higher than the standard model expectation. We explain this, and the MiniBooNE and m…

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^{(*…
