A first study of the semi-leptonic decay of the Λ baryon [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1997
We present the preliminary results of the first Lattice study of the baryonic Isgur and Wise function obtained from the matrix element of the weak current between $Λ$-baryon external states. Its dependence on the heavy and light quark masses is studied. Some result on the semi-leptonic decay $Λ_b\toΛ_c +lν$ are given.

Semi-leptonic decays at the Belle and Belle II experiments [PDF]

open access: yes, 2022
© 2022 Daniel Adam FerlewiczThis thesis explores semi-leptonic decays of the type $B \to V L$ along two avenues; their contribution to high-precision tests and metrology of the Standard Model, and their potential for probing physics beyond the Standard ...

Highlight of Charm Physics at BESIII

open access: yesEPJ Web of Conferences, 2014
In this talk, we present the recent results of charm physics from the BESIII collaboration. This talk covers the studies of the leptonic and semi-leptonic decays of D mesons, and the measurement of the strong phase difference based on the quantum ...

Radiative B decay spectrum: DGE at NNLO. [PDF]

open access: yes, 2007
We compute the differential ¯B → Xsγ decay width in the Standard Model as a function of the photon energy using Dressed Gluon Exponentiation (DGE).

SCET sum rules for Λ b → Λℓ + ℓ − , Λγ decays

open access: yesJournal of High Energy Physics
We construct light-cone sum rules for various types of effective form factors in the Λ b → Λℓ + ℓ − and Λ b → Λγ decays by analyzing vacuum-to-Λ b (or γ *-to-Λ b ) correlation functions with the light Λ-baryon interpolating current.

Non-Leptonic Weak Decays of B Mesons [PDF]

open access: yes, 1997
We present a detailed study of non-leptonic two-body decays of B mesons based on a generalized factorization hypothesis. We discuss the structure of non-factorizable corrections and present arguments in favour of a simple phenomenological description of ...

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

open access: yes
We derive the parameterization formula for partial wave analyses of charmed meson semi-leptonic decays with consideration of the effects caused by the lepton mass.

Total decay rates of B mesons at NNLO-QCD

open access: yesJournal of High Energy Physics
We update the Standard Model (SM) predictions for the lifetimes of the B +, B d and B s mesons within the heavy quark expansion (HQE), including the recently determined NNLO-QCD corrections to non-leptonic decays of the free b-quark.
