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 ...

Testing lepton flavor universality at the Electron-Ion Collider

Journal of High Energy Physics
Measurements of b → cτ − ν ¯ τ $$ b\to {c\tau}^{-}{\overline{\nu}}_{\tau } $$ transitions at colliders are highly motivated for testing lepton flavor universality (LFU), a cornerstone hypothesis of the Standard Model (SM).
