Abstract The ATLAS detector is installed in its experimental cavern at Point 1 of the CERN Large Hadron Collider. During Run 2 of the LHC, a luminosity of ℒ = 2 × 10 34 cm -2 s -1 was routinely achieved at …

Using $pp$ collision data collected by LHCb at center-of-mass energies $\sqrt{s}=7\text{ }\text{ }\mathrm{TeV}$ and 8 TeV, corresponding to an integrated luminosity of $3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, the ratio of the branching fraction of the ${B}_{c}^{+}\ensuremath{\rightarrow}\ensuremath{\psi}(2S){\ensuremath{\pi}}^{+}$ decay relative to that of the ${B}_{c}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\ensuremath{\pi}}^{+}$ decay …

Measurements are presented of the $CP$ violation observables $S$ and $C$ in the decays of ${B}^{0}$ and ${\overline{B}}^{0}$ mesons to the $J/\ensuremath{\psi}{K}_{S}^{0}$ final state. The data sample corresponds to an integrated luminosity of $3.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the LHCb experiment in …

The angular distributions and the partial branching fraction of the decay ${B}^{0}\ensuremath{\rightarrow}{K}^{*0}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ are studied by using an integrated luminosity of $0.37\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected with the LHCb detector. The forward-backward asymmetry of the muons, ${A}_{\mathrm{FB}}$, the fraction of longitudinal polarization, …
