(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 $|V_{cs(d)}|$ and form factor $f_{D_{(s)}}$ in the world based on 2.93 fb$^{-1}$ and 3.19 fb$^{-1}$ data taken at center-of-mass energies $\sqrt{s ...

Semi-leptonic decays heavy-light to heavy light [PDF]

Nuclear Physics B - Proceedings Supplements, 1999
We present results for the QCD matrix elements involved in semi-leptonic decays of B-mesons into pseudo scalar heavy light states. The application of NRQCD heavy quarks allows for quark masses around the physical b-quark. We investigate the dependence of

Constraining |V cs | and physics beyond the Standard Model from exclusive (semi)leptonic charm decays [PDF]

Journal of High Energy Physics
We 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 ...

Predictions and Tests for Semi-leptonic Decays of Beauty Hadrons

International Journal of Modern Physics A
We make predictions and propose tests for the semi-leptonic decays $B\to D^{(*)} l \bar{\nu}_l$ and $\Lambda_b\to \Lambda_c l \bar{\nu}_l$, with $l$ = $e$, $\mu$ and $\tau$.

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 ...

Semi-leptonic decays of charmed baryons [PDF]

Nuclear Physics B, 1976
Abstract We present estimates of semi-leptonic decays of the charmed 1+ 2 baryons, members of the SU(3) 3∗ and 6 multiplets, into ordinary 1+ 2 and 3+ 2 baryons. We give general expressions for decay rates and the mass M(B+l) spectra.

Exclusive semi-leptonic decays of bottom baryons

Physics Letters B, 1990
Abstract We calculate the exclusive semi-leptonic bottom baryon decays Λ b →Λ c +l − + v l , Σ b → Σ c +l − + v l and Σ b →Σ c ∗ +l − + v l in the spectator quark model. The helicity structure of the baryonic current transitions Λb→Λc, Σ
