A massive right-handed sterile neutrino in three-body $B ˉ \to D^{*} ℓ^{-} N ˉ_{R}$ decays - a Monte Carlo simulation study

Bhubanjyoti Bhattacharya, Thomas E. Browder, Lucien M. Cremaldi +6

We investigate the differential decay distributions of $B ˉ \to D^{*} ℓ^{-} N ˉ_{R}$ , where $N_{R}$ is a heavy right-handed neutrino (RHN) and $ℓ = e, μ$ . We employ a newly de…

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…

Exploring new physics in the angular distribution of $B ˉ \to D^{*} (\to D π) τ^{-} (\to V^{-} ν_{τ}) ν ˉ_{τ}$

Si-Yuan Liu, Alakabha Datta, Xian-Wei Kang

The decays $B ˉ \to D^{*} τ^{-} ν ˉ_{τ}$ provide sensitive probes of new physics in the $b \to c τ ν$ transition. We discuss the effects of new physics in the decay cha…

Axion-like particles and sterile neutrinos solve the $B \to K ν ν ˉ$ and $B \to π K$ puzzles

Bhubanjyoti Bhattacharya, Alakabha Datta, Girish Kumar +1

The recent measurement of the branching ratio of $B^{+} \to K^{+} + inv$ (where ``inv'' denotes invisible states) by the Belle II collaboration is enhanced relative to the sta…

Distinguishing between Dirac and Majorana neutrinos at FASER

ShivaSankar K. A., Alakabha Datta, Danny Marfatia

Some of the simplest models for the origin of neutrino mass involve right-handed neutrinos (RHNs), which could be either Dirac or Majorana particles - a distinction that has profou…

The generic basis and flavour non-universal SMEFT

Alakabha Datta, Jean-François Fortin, Jacky Kumar +3

Whenever an anomaly in the flavour sector appears, analyses are performed examining whether it can be explained by adding a small number of carefully-chosen flavour non-universal f…
