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 ...

Inclusive semileptonic B s 0 $$ {B}_s^0 $$ meson decays at the LHC via a sum-of-exclusive modes technique: possibilities and prospects

Journal of High Energy Physics
We propose an approach for measuring the moments of the hadronic invariant mass distribution in semileptonic B s 0 $$ {B}_s^0 $$ meson decays using a sum-of-exclusive technique. Using the present and foreseen knowledge about exclusive semileptonic B s 0 $
