Disentangling left-handed and right-handed neutrino effects in B c → τ ν ¯ τ $$ {B}_c\to \tau {\overline{\nu}}_{\tau } $$ decay

Journal of High Energy Physics
Inspired by the anomalies in B → D ∗ τ ν ¯ τ $$ B\to {D}^{\left(\ast \right)}\tau {\overline{\nu}}_{\tau } $$ decay, in this work, we carefully study the influence of the most general dimension-six effective operators involving right-handed neutrinos on ...

An imperative study of the angular observables in Λ b → Λ c + → Λ π + ℓ − ν ¯ ℓ $$ {\Lambda}_b\to {\Lambda}_c^{+}\left(\to \Lambda {\pi}^{+}\right){\ell}^{-}{\overline{\nu}}_{\ell } $$ decay and probing the footprint of new physics

Journal of High Energy Physics
We study the four-fold angular distribution of the semileptonic Λ b → Λ c + → Λ π + ℓ − ν ¯ ℓ $$ {\Lambda}_b\to {\Lambda}_c^{+}\left(\to \Lambda {\pi}^{+}\right){\ell}^{-}{\overline{\nu}}_{\ell } $$ decay and find out analytical expressions for various ...

D → Pℓ + ℓ − decays assisted by QCD light-cone sum rules

Journal of High Energy Physics
We suggest a new method to analyse the rare D (s) → Pℓ + ℓ − decays (P = π, K), combining QCD light-cone sum rules (LCSR) with hadronic dispersion relations.

Constraining anomalous Wtb and related SMEFT couplings using low-energy and electroweak precision observables

Journal of High Energy Physics
We investigate constraints on couplings of Standard Model effective field theory (SMEFT) operators contributing to Wtb effective vertex at tree level. We study the one-loop level impact of these couplings on the low-energy flavour changing charged and ...
