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 $\tau$.

A unified scheme for calculating the exclusive semi-leptonic decays of hadrons

Journal of Physics G: Nuclear and Particle Physics
Exclusive semi-leptonic decays are a pivotal channel for exploring heavy-flavor physics, primarily because they are straightforwardly measurable experimentally.

$��_b$ semi-leptonic weak decays

2011
$ _b \rightarrow _c^{(*)}$ semi-leptonic decays are studied in details. Relevant helicity amplitudes are written down. Both unpolarized and polarized $ _b$ cases are considered. Decay angular distributions, asymmetry parameters and semileptonic decay rates are calculated, with numerical results using leading order results of the large $N_c$ and ...

Semi-leptonic decays on the lattice

Nuclear Physics B - Proceedings Supplements, 1991
Abstract We present our recent results for the semi-leptonic decays D → Klν, D → πlν, D? → ηlν and D? → Klν. We report on work in progress for D → K ∗ lν .

On sum rules for semi-leptonic b → c and b → u decays

Journal of High Energy Physics
The semi-leptonic b → clν processes are receiving a lot of attention, as the lepton flavor universality (LFU) violation has been hinted by the measured ratios RD∗\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts}

Semi-leptonic decays of the ξ0 hyperon

Nuclear Physics A, 1998
Abstract The KTeV experiment at Fermilab was used to observe neutral Cascade hyperon beta decays. This is the first observation of such decays and a preliminary branching ratio for Ξ 0 → Σ + e − v ¯ e of 2.6 ± 0.2 (stat.) ± 0.3 (sys.) x 10−4 is reported.
