Precise measurement of the fs/fd ratio of fragmentation fractions and of Bs0 decay branching fractions

R. Aaij, Carlos Abellán Beteta, T. Ackernley, B. Adeva et autres

The ratio of the ${B}_{s}^{0}$ and ${B}^{0}$ fragmentation fractions, ${f}_{s}/{f}_{d}$, in proton-proton collisions at the LHC, is obtained as a function of $B$-meson transverse momentum and collision center-of-mass energy from the combined analysis of different $B$-decay channels measured by the LHCb experiment. …

Measurement of the B± production asymmetry and the CP asymmetry in B±→J/ψK± decays

R. Aaij, B. Adeva, M. Adinolfi, Z. Ajaltouni et autres

The ${B}^{\ifmmode\pm\else\textpm\fi{}}$ meson production asymmetry in $pp$ collisions is measured using ${B}^{+}\ensuremath{\rightarrow}{\overline{D}}^{0}{\ensuremath{\pi}}^{+}$ decays. The data were recorded by the LHCb experiment during Run 1 of the LHC at center-of-mass energies of $\sqrt{s}=7$ and 8 TeV. The production asymmetries, integrated over transverse momenta …
