Predictions and Tests for Semi-Leptonic Decays of Beauty Hadrons [PDF]

International Journal of Modern Physics A
We make predictions and propose tests for the semi-leptonic decays [Formula: see text] and [Formula: see text], with l = e, [Formula: see text] and [Formula: see text]. Preliminarily, we study such processes according to the [Formula: see text] scheme, which helps interpreting the results of previous analyses.

QED Effects in Inclusive Semi-Leptonic B Decays

Journal of High Energy Physics, 2023
A bstract 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

QED factorization of two-body non-leptonic and semi-leptonic B to charm decays

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 − $$ {\

D- and B-meson semi-leptonic decays [PDF]

Nuclear Physics B - Proceedings Supplements, 1994
Recent results for semi-leptonic decays of $D$ and $B$ mesons at $β=6.4$, using the Wilson action, and at $β=6.0$, using the Clover action, are reported.

Searching for New Physics in the Differential Decay Width of a Λb Semi-Leptonic Decay

Modern Physics Letters A, 2022
We propose to investigate the effects of new physics in the semi-leptonic sequential decay [Formula: see text]. First, we write the general, model-independent, non-covariant expression of the differential decay width of the process. Then, we calculate that observable according to three different types of new physics interactions, which might explain ...

Searching for new physics in semi-leptonic baryon decays [PDF]

Modern Physics Letters A, 2017
We propose two different and complementary observables for singling out possible signals of physics beyond the Standard Model (SM) in the semi-leptonic decays [Formula: see text], both with the [Formula: see text] lepton and with a light lepton. The two observables are the partial decay width and a T-odd asymmetry, whose respective sensitivities to ...

Quantum entanglement and Bell inequality violation in semi-leptonic top decays

Journal of High Energy Physics
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 ...

B → D 0 ∗ $$ B\to {D}_0^{\ast } $$ and B s → D s 0 ∗ $$ {B}_s\to {D}_{s0}^{\ast } $$ form factors from QCD light-cone sum rules

Journal of High Energy Physics, 2023
We present the first application of QCD light-cone sum rules (LCSRs) with B (s)-meson distribution amplitudes to the B s → D s 0 ∗ $$ {B}_{(s)}\to {D}_{(s)0}^{\ast } $$ form factors, where D s 0 ∗ $$ {D}_{(s)0}^{\ast } $$ is a charmed scalar meson.

(Semi-)leptonic decays of $D_{(s)}$ Mesons at BESIII [PDF]

Proceedings of ALPS 2019 An Alpine LHC Physics Summit — PoS(ALPS2019), 2021
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.
