Searching for new physics in semi-leptonic baryon decays [PDF]

Modern Physics Letters A, 2017
We propose two different and complementary observables for singling out possible signals of physics beyond the Standard Model (SM) in the semi-leptonic decays [Formula: see text], both with the [Formula: see text] lepton and with a light lepton. The two observables are the partial decay width and a T-odd asymmetry, whose respective sensitivities to ...

Hints of R-parity violation in B decays into $\tau \nu$

, 2013
In this article we show that the recently observed enhanced semi-leptonic and leptonic decay rates of the B meson into \tau \nu modes can be explained within the frame work of R-parity violating (RPV) MSSM.

Heavy quark symmetry behind b → c semileptonic sum rule

Journal of High Energy Physics
Lepton flavor universality violations in semileptonic b → c transitions have garnered attention over a decade. For $${R}_{{H}_{c}}={\text{BR}}\left({H}_{b}\to {H}_{c}\tau {\overline{\nu }}_{\tau }\right)/{\text{BR}}\left({H}_{b}\to {H}_{c}{\ell ...

Highlight of Charm Physics at BESIII

EPJ 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 ...

Critical Analysis of Theoretical Estimates for $B$ to Light Meson Form Factors and the $B \to \psi K(K^{\ast})$ Data

, 1994
We point out that current estimates of form factors fail to explain the non-leptonic decays $B \to \psi K(K^{\ast})$ and that the combination of data on the semi-leptonic decays $D \to K(K^{\ast})\ell \nu$ and on the non-leptonic decays $B \to \psi K(K^{\

Total decay rates of B mesons at NNLO-QCD

Journal 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.
