Massive right-handed neutrinos in $B ˉ \to D^{*} τ X ˉ$ decay

Nilakshi Das, Alakabha Datta, Tejhas Kapoor +2

We explore signatures of a massive right-handed neutrino (RHN) in angular distributions of $B ˉ \to D^{*} (\to D π) τ (\to π ν_{τ}) X ˉ$ decays, where $X$ is an invisible state. W…

New physics searches via angular distributions of $B ˉ \to D^{*} (\to D π) τ (\to ℓ ν_{τ} ν ˉ_{ℓ}) ν ˉ_{τ}$ decays

Bhubanjyoti Bhattacharya, Thomas E. Browder, Alakabha Datta +3

The study of $B ˉ \to D^{*} τ ν ˉ_{τ}$ angular distribution can be used to obtain information about new physics (or beyond the Standard Model) couplings, which are motivated by…

Neutrino Nonstandard Interactions and Lepton Flavor Universality violation at SND@LHC via charm production

Bhubanjyoti Bhattacharya, Alakabha Datta, Elena Graverini +3

In this work, we explore the effect of neutrino nonstandard interactions (NSI) involving the charm quark at SND@LHC. Using an effective description of new physics in terms of four-…

$B \to K ν ν ˉ$ , 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…
