First measurement of the $C\!P$-violating phase in ${{B} ^0_{s}} \!\rightarrow {{J /\psi }} (\rightarrow e ^+e ^-$)$\phi $ decays / LHCb Collaboration
A flavour-tagged time-dependent angular analysis of $B^0_s\to J/\psi\phi$ decays is presented where the $J/\psi$ meson is reconstructed through its decay to an $e^+e^-$ pair. The analysis uses a sample of $pp$ collision data recorded with the LHCb experiment at centre-of-mass energies of $7$ and $8$ TeV, corresponding to an integrated luminosity of $3$ fb$^{-1}$. [...]

A Comparison of CPU and GPU implementations for the LHCb Experiment Run 3 Trigger / LHCb Collaboration
The LHCb experiment at CERN is undergoing an upgrade in preparation for the Run 3 data taking period of the LHC. As part of this upgrade the trigger is moving to a fully software implementation operating at the LHC bunch crossing rate. [...]

First observation of the decay $B_s^0 \to K^-\mu^+\nu_\mu$ and measurement of $|V_{ub}|/|V_{cb}|$ / LHCb Collaboration
The first observation of the suppressed semileptonic $B_s^0 \to K^-\mu^+\nu_\mu$ decay is reported. Using a data sample recorded in $pp$ collisions in 2012 with the LHCb detector, corresponding to an integrated luminosity of 2 $\mathrm{fb}^{-1}$, the branching fraction $\mathcal{B}(B_s^0 \to K^-\mu^+\nu_\mu)$} is measured to be $(1.06\pm0.05~(\mathrm{stat})\pm0.08~(\mathrm{syst}))\times 10^{-4}$, where the first uncertainty is statistical and the second one represents the combined systematic uncertainties.

Search for long-lived particles decaying to $e^{\pm} \mu^{\mp} \nu$ / LHCb Collaboration
Long-lived particles decaying to $e^\pm \mu^\mp \nu$, with masses between 7 and 50 GeV/c$^2$ and lifetimes between 2 and 50 ps, are searched for by looking at displaced vertices containing electrons and muons of opposite charges. The search is performed using 5.4 fb$^{-1}$ of $pp$ collisions collected with the LHCb detector at a centre-of-mass energy of $\sqrt{s} = 13$ TeV. [...]

Measurement of the CKM angle $\gamma$ in $B^\pm\to D K^\pm$ and $B^\pm \to D \pi^\pm$ decays with $D \to K_\mathrm S^0 h^+ h^-$ / LHCb Collaboration
A measurement of $CP$-violating observables is performed using the decays ${B^\pm\to D K^\pm}$ and ${B^\pm\to D \pi^\pm}$, where the $D$ meson is reconstructed in one of the self-conjugate three-body final states $K_{\mathrm S}^0\pi^+\pi^-$ and $K_{\mathrm S}^0K^+K^-$ (commonly denoted $K_{\mathrm S}^0 h^+h^-$). The decays are analysed in bins of the $D$-decay phase space, leading to a measurement that is independent of the modelling of the $D$-decay amplitude. [...]

Study of the lineshape of the $\chi_{c1}(3872)$ state / LHCb Collaboration
A study of the lineshape of the $χ_{c1}(3872)$ state is made using a data sample corresponding to an integrated luminosity of $3\,$fb$^{-1}$ collected in $pp$ collisions at centre-of-mass energies of 7 and 8\,TeV with the LHCb detector. Candidate $χ_{c1}(3872)$ and $ψ(2S)$ mesons from b-hadron decays are selected in the $ J/ψπ^+ π^-$ decay mode. [...]

Measurement of $Z\rightarrow\tau^+\tau^-$ production in proton-proton collisions at $\sqrt{s} = 8$ TeV / LHCb Collaboration
A measurement of $Z\rightarrow\tau^+\tau^-$ production cross-section is presented using data, corresponding to an integrated luminosity of 2 fb$^{-1}$, from $pp$ collisions at $\sqrt{s}=8$ TeV collected by the LHCb experiment. The $\tau^+\tau^-$ candidates are reconstructed in final states with the first tau lepton decaying leptonically, and the second decaying either leptonically or to one or three charged hadrons. [...]

Performance benchmark of LHCb code on state-of-the-art x86 architectures / Perez, D H Campora (CERN) ; Neufeld, N (CERN) ; Schwemmer, R (CERN)
For Run 2 of the LHC, LHCb is replacing a significant part of its event filter farm with new compute nodes. For the evaluation of the best performing solution, we have developed a method to convert our high level trigger application into a stand-alone, bootable benchmark image. [...]
