Semi-leptonic B decays into higher charmed resonances [PDF]

, 1996
We apply HQET to semi-leptonic $B$ meson decays into a variety of excited charm states. Using three realistic meson models with fermionic light degrees of freedom, we examine the extent that the sum of exclusive single charmed states account for the ...

, 2017
By analyzing 482 pb$^{-1}$ of $e^+e^-$ collision data collected at the center-of-mass energy $\sqrt s=4.009$ GeV with the BESIII detector, we measure the %absolute branching fractions for the semi-leptonic decays $D_{s}^{+}\to \phi e^{+}\nu_{e}$, $\phi ...

Leptonic and semi-leptonic B decays [PDF]

Nuclear Physics B - Proceedings Supplements, 2001
We present results for the semi-leptonic and leptonic decays of B mesons. These non-perturbative matrix elements are important for constraining the CKM matrix. Results are presented for the pseudoscalar and vector decay constants, as well as flavour breaking ratios and heavy quark symmetry relations.

Anomalies in b → s Transitions and Dark Matter

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
Since 2013, the LHCb collaboration has reported on the measurement of several observables associated with b → s transitions, finding various deviations from their predicted values in the Standard Model. These include a set of deviations in branching ratios and angular observables, as well as in the observables RK and RK⁎, specially built to test the ...

Towards the precision measurement of CP violation in B → D * μν decays at LHCb

Journal of High Energy Physics, 2023
Measurement of CP-violating observables in semileptonic decays is a sensitive null-test of the Standard Model: any CP violation would be an unambiguous sign of New Physics effects.

Study of B¯d,s⁎0→Dd,s+M- Decays with QCD Factorization Approach

Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016
Motivated by the b‐physics experiments at running LHC and upcoming SuperKEKB/Belle‐II, the nonleptonic B¯q⁎0→Dq+M- (q = d, s and M = π, K, ρ, K⁎) weak decays are studied within QCD factorization framework. The observables of these decay modes are first predicted.

Charm physics confronts high-p T lepton tails

Journal of High Energy Physics, 2020
We present a systematic survey of possible short-distance new-physics effects in (semi)leptonic charged- and neutral-current charmed meson decays. Using the Standard Model Effective Field Theory (SMEFT) to analyze the most relevant experimental data at ...

Revisiting semileptonic B meson decays at next-to-next-to-leading order

Journal of High Energy Physics, 2023
We compute next-to-next-to-leading order corrections to the semileptonic decay rate of B mesons for arbitrary values of the final-state quark mass. For the contribution with one massive quark in the final state, we extend the literature result and obtain
