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

open access: yesNuclear Physics B - Proceedings Supplements, 2000
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 the form factors on the external momenta and looked at the mass dependence at zero recoil.

Revisiting Minimal Lepton Flavour Violation in the light of leptonic CP violation

open access: yesJournal of High Energy Physics, 2017
The Minimal Lepton Flavour Violation (MLFV) framework is discussed after the recent indication for CP violation in the leptonic sector. Among the three distinct versions of MLFV, the one with degenerate right-handed neutrinos will be disfavoured, if this

Semi-leptonic decays of charmed baryons [PDF]

open access: yesNuclear 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.

Probing lepton universality with (semi)-leptonic B decays [PDF]

open access: yesSciPost Physics Proceedings, 2019
The most recent measurements of the observables $R_{D^{(*)}}$ are in tension with the Standard Model offering hints of New Physics in $b\rightarrow c \ell \bar{\nu}_{\ell}$ transitions.

Exclusive semi-leptonic decays of bottom baryons

open access: yesPhysics 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

Search for heavy neutral leptons in decays of W bosons using leptonic and semi-leptonic displaced vertices in s $$ \sqrt{s} $$ = 13 TeV pp collisions with the ATLAS detector

open access: yesJournal 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 ...

Lepton mass correction in partial wave analyses of charmed meson semi-leptonic decays [PDF]

open access: yesChinese Physics C, High Energy Physics & Nuclear Physics, 2023
We derive a parameterization formula for the partial wave analyses of charmed meson semi-leptonic decays while considering the effects of lepton mass. Because the proposed super-tau-charm factory will reach a significantly enhanced luminosity and BESIII ...
