“…Additional experimental information on the semileptonic B decays comes from BaBar measurements. Studies of the B → D ( * ) ν process were presented in [141][142][143][144][145][146][147]. In the first three references, the question of the lepton flavor universality was addressed ( = τ) and the measurement of R D and R D * was performed.…”

“…The significance of the measurement reached 4σ level. The CP-violation topic was then discussed in further publications for the neutral [308][309][310][311][312][313][314][315][316] and also charged B meson [317][318][319][320]. Both indirect (i.e., involving particle-antiparticle oscillations) and direct CP violations were seen with relevant significance.…”

“…Several texts present measurements where the branching fraction and the CP asymmetries were addressed at the same time [321][322][323][324][325][326]. In addition to the direct CP violation measurements, the closely related measurements of the CKM angles α and γ were presented in [327][328][329][330].…”

B Meson Decays in the Covariant Confined Quark Model

et al. 2023

The aim of this text is to present the covariant confined quark model (CCQM) and review its applications in the decays of B mesons. We do so in the context of existing experimental measurements and theoretical results of other authors, which we also review. The physics principles are, in detail, exposed for the CCQM; the other results (theoretical and experimental) are surveyed in an enumerative way with comments. We proceed by considering, successively, three categories of decay processes: leptonic, semileptonic and non-leptonic.

“…The concept of multiquark states composed of more then three quarks hypothesized decades ago [1] was for the first time confirmed in 2003 where multiquark state candidates were measured by the BES [2], BaBar [3], and Belle [4] experiments. The latter observation, seen in the π + π − J/ψ invariant mass spectrum, was the first observation of a charmonium-like state X(3872), which did not fit expectations of existing quark models for any conventional hadronic particle.…”

Dynamical Approach to Decays of XYZ States

et al. 2020

We review the existing results on the exotic XYZ states and their decays obtained within the confined covariant quark model. This dynamical approach is based on a non-local Lagrangian of hadrons with quarks, has built-in quark confinement, and is suited well for the description of different multiquark states, including the four quark ones. We focus our analysis on the various decay modes of five exotic states, X ( 3872 ) , Z c ( 3900 ) , Y ( 4260 ) , Z b ( 10610 ) , and Z b ′ ( 10650 ) , aiming to clarify their internal quark structures. By considering mostly branching fractions and decay widths using the molecular-type or the tetraquark-type interpolating currents, conclusions about the nature of these particles are drawn: the molecular structure is favored for Z c ( 3900 ) , Z b ( 10610 ) , and Z b ′ ( 10650 ) and the tetraquark for X ( 3872 ) and Y ( 4260 ) .
