Tau polarimetry in B meson decays [PDF]

open access: yesSciPost Physics Proceedings, 2019
This article summarizes recent developments in $B\to D^{(\ast)}\tau\nu$ decays. We explain how to extract the tau lepton's production properties from the kinematics of its decay products.

Baryonic B Meson Decays

open access: yesAdvances in High Energy Physics, 2022
We review the two- and three-body baryonic B decays with the dibaryon (BB′¯) as the final states. Accordingly, we summarize the experimental data of the branching fractions, angular asymmetries, and CP asymmetries.

A novel observable for CP violation in multi-body decays and its application potential to charm and beauty meson decays

open access: yesPhysics Letters B, 2021
A novel observable measuring the CP asymmetry in multi-body decays of heavy mesons, which is called the forward-backward asymmetry induced CP asymmetry (FBI-CPA), ACPFB, is introduced. This observable has the dual advantages that 1) it can isolate the CP

B meson decays [PDF]

open access: yesPMC Physics A, 2009
We discuss the most important Physics thus far extracted from studies of B meson decays. Measurements of the four CP violating angles accessible in B decay are reviewed as well as direct CP violation. A detailed discussion of the measurements of the CKM elements V_{cb} and V_{ub} from semileptonic decays is given, and the differences between resulting ...

Measurement of CP observables in B± → D(*)K± and B± → D(*) π ± decays using two-body D final states

open access: yesJournal of High Energy Physics, 2021
Measurements of CP observables in B ± → D (*) K ± and B ± → D (*) π ± decays are presented, where D (∗) indicates a neutral D or D ∗ meson that is an admixture of meson and anti-meson states.

Renormalization-group evolution of the none-local matrix element of B-meson in QCD and B → π transition form factor

open access: yesNuclear Physics B, 2021
We consider the renormalization-group evolution of the matrix element of 〈0|q¯(z)β[z,0]b(0)α|B¯〉, which can be used to define the distribution amplitudes for B meson and widely applied in studies of B meson decays. The contribution to the renormalization

The fate of $$\mathbf{V}_\mathbf{1}$$ V 1 vector leptoquarks: the impact of future flavour data

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Motivated by the recent experimental progress on the B-meson decay anomalies (in particular the angular observables in $$B\rightarrow K^*\mu \mu $$ B → K ∗ μ μ ), we rely on a simplified-model approach to study the prospects of vector leptoquarks in what

Analysis of the b 1 meson decay in local tensor bilinear representation

open access: yesJournal of High Energy Physics, 2018
We explore the validity of vector meson dominance in the radiative decay of the b 1(1235) meson. In order to explain the violation of the vector meson dominance hypothesis in this decay process, we investigate a model where the b 1 meson strongly couples

The nonleptonic decays of b-flavored mesons to S-wave charmonium and charm meson states

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The detection of radially excited charmonium and charm meson states, and measurement of heavy meson decays, particularly $$B_c^+\rightarrow J/\psi D_s^+$$ B c + → J / ψ D s + and $$B_c^+\rightarrow J/\psi D_s^{*+}$$ B c + → J / ψ D s ∗ + , by the LHCb ...
