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.

CP violation in decays into states with neutral kaons

Journal of High Energy Physics
CP violation in the kaon system can manifest itself in decays to final states containing neutral kaons. The effect is governed by an efficiency function that reflects the specific experimental setup.

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 ...

TeV-scale scalar leptoquarks motivated by B anomalies improve Yukawa unification in SO(10) GUT

Journal of High Energy Physics
It is common practice to explain deviations between data and Standard-Model (SM) predictions by postulating new particles at the TeV scale ad-hoc. This approach becomes much more convincing, if one successfully embeds the postulated particles into a UV ...

Studying Rare Semi-Leptonic Decay of Hyperons

The decay of hyperons proceeds via the weak transition of a strange quark into an up quark. The strength of this transition is governed by the Cabibbo angle, a fundamental parameter of the Standard Model. Determining this parameter through different processes provides an important test of the model’s consistency.
