Probing Signatures of Right-Handed Neutrinos via $b \to s I^½ I^ˉ ½$ Decays

Prisha, Priyanka Boora, Dinesh Kumar +1

The recent Belle II measurement of $B (B^{+} \to K^{+} I^½ I^ˉ ½)$ , which deviates from the Standard Model prediction, provides a strong motivation to search for New Physics in $…

A comprehensive study of $I^_{c}^{-} \to I^ (\to p I ¨ ) I^¼^{-} I^ˉ ½_{I^} ¼$ incorporating SMEFT implications and right-handed neutrino

Priyanka Boora, Siddhartha Karmakar, Dinesh Kumar +1

We present a comprehensive analysis of the decay $I^_{c}^{-} \to I^ (\to p I ¨ ) I^¼^{-} I^ˉ ½_{I^} ¼$ within a model-independent effective field theory framework. Previous studies have been re…

New physics effects in semileptonic $B_{s} ˉ \to K^{*+} (\to K I ¨ ) ℓ^{-} I^ˉ ½_{ℓ}$ decay

Shabana Khan, Dinesh Kumar

We analyze the new physics effects in semileptonic $B_{s} ˉ \to K^{*+} (\to K I ¨ ) ℓ^{-} I^ˉ ½_{ℓ}$ decay induced by the $b \to u ℓ I^½_{ℓ}$ quark level transition. We consi…

New Physics effects with right-handed neutrinos in semileptonic decay $B_{c}^{+} \to B_{s} I^¼^{+} I^½_{I^} ¼$

Priyanka Boora, Dinesh Kumar, Kavita Lalwani

We extend the Standard Model with the general effective Hamiltonian for the quark level transition $c \to s ℓ I^½$ with a complete set of four fermion operators including right-h…
