Abstract The standard model of particle physics currently provides our best description of fundamental particles and their interactions. The theory predicts that the different charged leptons, the electron, muon and tau, have identical electroweak interaction strengths. Previous measurements have shown that a …

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. …

In an amplitude analysis of the ${B}^{+}\ensuremath{\rightarrow}{D}^{+}\phantom{\rule{0}{0ex}}{D}^{\ensuremath{-}}\phantom{\rule{0}{0ex}}{K}^{+}$ decay, the LHCb Collaboration finds evidence for new spin-0 and spin-1 exotic open-charm and open_strangeness resonances in the ${D}^{\ensuremath{-}}\phantom{\rule{0}{0ex}}{K}^{+}$ channel with masses around 2.9 GeV. These resonances must contain at least four quarks, namely an …
