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

NLO QCD corrections to off-shell top–antitop production with semi-leptonic decays at lepton colliders [PDF]
The European Physical Journal C, 2023 The study of top-quark properties will be a central aspect of the physics programme of any future lepton collider. In this article, we investigate the production of top-quark pairs in the semi-leptonic decay channel in $${\textrm{e}}^{+}\textrm{e ...

Inclusive semi-leptonic decays of charmed mesons with Möbius domain wall fermions [PDF]
Proceedings of The 39th International Symposium on Lattice Field Theory — PoS(LATTICE2022), 2022 We perform a non-perturbative lattice calculation of the decay rates for inclusive semi-leptonic decays of charmed mesons. In view of the long-standing tension in the determination of the CKM matrix elements | 𝑉 𝑢𝑏 | and | 𝑉 𝑐𝑏 | from exclusive and ...

Composition of the inclusive semi-leptonic decay of B meson [PDF]
Proceedings of The 38th International Symposium on Lattice Field Theory — PoS(LATTICE2021), 2021 Utilizing the approach recently proposed for the inclusive semi-leptonic decay rate on the lattice, we compute the differential decay rate of a $B_s$ meson for various kinematical channels. The results are compared with the contributions from the ground states (D and D^*) as well as from the orbitally excited states (D^**'s).

Searching for New Physics in the Differential Decay Width of a Lambda_b Semi-leptonic Decay [PDF]
Modern Physics Letters A, 2022 We propose to investigate the effects of new physics in the semi-leptonic sequential decay [Formula: see text]. First, we write the general, model-independent, non-covariant expression of the differential decay width of the process. Then, we calculate that observable according to three different types of new physics interactions, which might explain ...

Revisiting inclusive decay widths of charmed mesons
Journal of High Energy Physics, 2022 Determining for the first time the Darwin operator contribution for the non-leptonic charm-quark decays and using new non-perturbative results for the matrix elements of ∆C = 0 four-quark operators, including eye-contractions, we present a comprehensive ...
