Measurement of the inclusive semileptonic B meson branching fraction in 62.8 fb1 of Belle II data / Belle-II Collaboration
We report a measurement of the branching fraction of inclusive semileptonic B meson decays BXcν in Υ(4S)BˉB~data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy e+e collider and corresponding to 62.8 fb1 of integrated luminosity. [...]

Exclusive BXuν Decays with Hadronic Full-event-interpretation Tagging in 62.8 fb1 of Belle II Data / Belle-II Collaboration
We present a reconstruction in early data of the semileptonic decay B+π0+ν, and first results of a reconstruction of the decays B+ρ0+ν and B0ρ+ν in a sample corresponding to 62.8 fb1 of Belle II data using hadronic B-tagging via the full-event-interpretation algorithm. [...]

Search for a light Higgs boson in single-photon decays of Υ(1S) using Υ(2S)π+πΥ(1S) tagging method / Belle Collaboration
We search for a light Higgs boson (A0) decaying into a τ+τ or μ+μ pair in the radiative decays of Υ(1S). The production of Υ(1S) mesons is tagged by Υ(2S)π+πΥ(1S) transitions, using 158 million Υ(2S) events accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. [...]

Measurement of the ratio of branching fractions of the decays Λ0bψ(2S)Λ and Λ0bJ/ψΛ / LHCb Collaboration
Using pp collisions corresponding to 3fb1 integrated luminosity, recorded by the LHCb experiment at centre-of-mass energies of 7 and 8TeV, the ratio of branching fractions B(Λ0bψ(2S)Λ)/B(Λ0bJ/ψΛ)=0.513±0.023(stat)±0.016(syst)±0.011(B) is determined. The first uncertainty is statistical, the second is systematic and the third is due to the external branching fractions used..

First Measurement of Charm Production in its Fixed-Target Configuration at the LHC / LHCb Collaboration
The first measurement of heavy-flavour production by the LHCb experiment in its fixed-target mode is presented. The production of J/ψ and D0 mesons is studied with beams of protons of different energies colliding with gaseous targets of helium and argon with nucleon-nucleon centre-of-mass energies of sNN=86.6 and 110.4 GeV, respectively.
