Complete O α s 2 $$ \mathcal{O}\left({\alpha}_s^2\right) $$ corrections to the leptonic invariant mass spectrum in b → X c l ν ¯ l $$ b\to {X}_cl{\overline{\nu}}_l $$ decay by Mateusz Czaja, Mikołaj Misiak, Abdur Rehman

“…Abstract In the determination of the Cabibbo-Kobayashi-Maskawa matrix element |V cb | from inclusive semileptonic B-meson decays, moments of the leptonic invariant mass spectrum constitute valuable observables. …”

Probing third-generation New Physics with K→πνν¯ and B→K(⁎)νν¯ by L. Allwicher, M. Bordone, G. Isidori, G. Piazza, A. Stanzione

“…We find that the slight excess observed in both channels supports the hypothesis of non-standard TeV dynamics of this type, as also hinted at by other B-meson decays, consistently with bounds from colliders and electroweak observables. …”

Effective theory approach to new physics with flavour: general framework and a leptoquark example by Marzia Bordone, Oscar Catà, Thorsten Feldmann

“…In this paper, we address this issue in view of the recently observed “flavour anomalies” in B-meson decays, which we take as a motivation to develop a general framework that allows us to systematically reduce the number of flavour parameters in the EFT. …”

B ¯ → D ¯ D $$ \overline{B}\to \overline{D}D $$ decays and the extraction of f d /f u at hadron colliders by Jonathan Davies, Martin Jung, Stefan Schacht

“…Importantly, allowing in the same fit for the production fractions of charged and neutral B mesons to be different, we find f d /f u = 0.86 ± 0.05, which is 2.5σ away from unity, which, if confirmed, would have important phenomenological consequences.…”

Statistical production of Bc mesons in heavy-ion collisions at the LHC energy by Shouxing Zhao, Min He

“…We study the production of Bc mesons via c and bottom (b) quark recombination in a statistical fashion by placing Bc in the position of a member of the family of open b hadrons, which allows us to make quantitative predictions for the modifications of the production fraction (fc) of Bc mesons and its relative production to B mesons in sNN=5.02TeV Pb-Pb collisions with respect to proton-proton (pp) collisions at the same energy. …”
