QED effects in inclusive semi-leptonic B decays [PDF]
Journal of High Energy Physics, 2023 We analyse in detail the QED corrections to the total decay width and the moments of the electron energy spectrum of the inclusive semi-leptonic B → X c eν decay. Our calculation includes short-distance electroweak corrections, the complete 𝒪(α) partonic

QED factorization of two-body non-leptonic and semi-leptonic B to charm decays [PDF]
Journal of High Energy Physics, 2021 The QCD×QED factorization is studied for two-body non-leptonic and semi-leptonic B decays with heavy-light final states. These non-leptonic decays, like B ¯ s 0 → D s + π − $$ {\overline{B}}_{(s)}^0\to {D}_{(s)}^{+}{\pi}^{-} $$ and B ¯ d 0 → D + K − $$ {\

Form factors for semi-leptonic B decays [PDF]
Proceedings of The 30th International Symposium on Lattice Field Theory — PoS(Lattice 2012), 2012 We report on form factors for the B->K l^+ l^- semi-leptonic decay process. We use several lattice spacings from a=0.12 fm down to 0.06 fm and a variety of dynamical quark masses with 2+1 flavors of asqtad quarks provided by the MILC Collaboration. These ensembles allow good control of the chiral and continuum extrapolations.

(Semi-)leptonic decays of D mesons at BESIII [PDF]
Proceedings of ALPS 2019 An Alpine LHC Physics Summit — PoS(ALPS2019), 2019 Leptonic and semi-leptonic D decays at BESIII contribute the most precise experimental measurement of |Vcs(d)| and form factor fD(s) in the world based on 2.93 fb−1 and 3.19 fb−1 data taken at center-of-mass energies s√=3.773 and 4.180~GeV, respectively.

Quantum entanglement and Bell inequality violation in semi-leptonic top decays [PDF]
Journal of High Energy Physics, 2023 Quantum entanglement is a fundamental property of quantum mechanics. Recently, studies have explored entanglement in the t t ¯ $$ t\overline{t} $$ system at the Large Hadron Collider (LHC) when both the top quark and anti-top quark decay leptonically ...

Constraining |V cs | and physics beyond the Standard Model from exclusive (semi)leptonic charm decays [PDF]
Journal of High Energy PhysicsWe study the available data on exclusive leptonic and semileptonic c → sℓ + ν decays within the Standard Model and beyond. Our analysis accounts for theory correlations between the relevant hadronic matrix elements through application of dispersive ...
