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.

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 neutral-current decays

Il Nuovo Cimento A, 1975
The possibility of testing neutral-current models in the strangeness-conserving semi-leptonic decays is discussed. The most reasonable experiment would seem to involve a search for parity-violating effects in Σ0→Λe+e-. However, we find anadditional order-of-magnitude suppression for this process due to the favored value of the mixing angle in the ...

$��_b$ 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 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.

Journal of High Energy Physics
A search is performed for long-lived heavy neutral leptons (HNLs), produced through the decay of a W boson along with a muon or electron. Two channels are explored: a leptonic channel, in which the HNL decays into two leptons and a neutrino, and a semi ...
