TLDR
Using a modified, retuned, Cornell potential that includes the running and large distance freezing of the strong coupling constant, the authors compute the spectroscopy, production mechanisms, and decays of excited meson.

The Vcb puzzle: An update

TL;DR: In this article, the authors discuss the impact of the recent untagged analysis of B 0 → D ⁎ l ν ¯ l decays by the Belle Collaboration on the extraction of the CKM element | V c b | and provide updated SM predictions for the b → c τ ν observables R (D ‎ ), P τ, and F L D .

Excited bottom-charmed mesons in a nonrelativistic quark model

TL;DR: In this paper, a nonrelativistic linear potential model was proposed to calculate the radiative transitions between the low-lying states of the mass spectrum up to the 6S$ multiplet with a nonlinear potential model and the wave functions from this model were used to evaluate the Okubo-Zweig-Iizuka (OZI) allowed two-body strong decays with the OZI model.

Landau equation and QCD sum rules for the tetraquark molecular states

TL;DR: In this article, it was shown that the Landau equation is of no use to study the Feynman diagrams in the QCD sum rules for the tetraquark molecular states; the fact is that the meson-meson scattering states cannot saturate the sum rules.

Bayesian fit analysis to full distribution data of $\bar B \to D^{(*)} \ell\bar\nu$: $|V_{cb}|$ determination and New Physics constraints

TL;DR: In this article, the authors investigated the semi-leptonic decays of B \to D^{(*)} \ell\bar u$ in terms of the HQET parameterization for the form factors, which is described with the heavy quark expansion up to Ω(1/m_c^2) beyond the simple approximation considered in the original CLN parameterization.
