High Energy Phys.) ; Chen, Bo (Beijing, Inst. High Energy Phys. ; Hunan U.) et al.
SALT, a new dedicated readout Application Specific Integrated Circuit (ASIC) for the Upstream Tracker, a new silicon detector in the Large Hadron Collider beauty (LHCb) experiment, has been designed and developed. It is a 128-channel chip using an innovative architecture comprising a low-power analogue front-end with fast pulse shaping and a 40 MSps 6-bit Analog-to-Digital Converter (ADC) in each channel, followed by a Digital Signal Processing (DSP) block performing pedestal and Mean Common Mode (MCM) subtraction and zero suppression.

Search for heavy neutral leptons in $W^+ \to \mu^+ \mu^{\pm} jet $ decays / LHCb Collaboration
A search is performed for heavy neutrinos in the decay of a $W$ boson into two muons and a jet. The data set corresponds to an integrated luminosity of approximately $3.0 \text{ fb}^{- 1}$ of proton-proton collision data at centre-of-mass energies of 7 and $8 \text{ TeV}$ collected with the LHCb experiment.

Observation of the $B_s^0 \rightarrow D^{\ast \pm} D^{\mp}$ decay / LHCb Collaboration
A search for the $B^0_s \!\rightarrow D^{*\pm} D^\mp$ decay is performed using proton-proton collision data at centre-of-mass energies of $7$, $8$ and $13\,\text{TeV}$ collected by the LHCb experiment, corresponding to an integrated luminosity of $9\,\text{fb}^{-1}$. The decay is observed with a high significance and its branching fraction relative to the $B^0 \!\rightarrow D^{*\pm} D^\mp$ decay is measured to be \begin{align*} \frac{\mathcal{B}(B_s^0 \rightarrow D^{\ast \pm} D^{\mp}) }{\mathcal{B}(B^0 \rightarrow D^{\ast \pm} D^{\mp}) } = 0.137 \pm 0.017 \pm 0.002 \pm 0.006 \,, \end{align*} where the first uncertainty is statistical, the second systematic and the third is due to the uncertainty on the ratio of the $B_s^0$ and $B^0$ hadronisation fractions..

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. [...]

Observation of the $\varLambda^{0}_{b}\to\varLambda^{+}_{c}K^{+}K^{-}\pi^{-}$ decay / LHCb Collaboration
The $\varLambda^{0}_{b}\to\varLambda^{+}_{c}K^{+}K^{-}\pi^{-}$ decay is observed for the first time using a data sample of proton-proton collisions at centre-of-mass energies of $\sqrt{s}=7$ and 8 $\rm{TeV}$ collected by the $\mbox{LHCb}$ detector, corresponding to an integrated luminosity of $3{\rm{fb}^{-1}}$. The ratio of branching fractions between the $\varLambda^{0}_{b}\to\varLambda^{+}_{c}K^{+}K^{-}\pi^{-}$ and the $\varLambda^{0}_{b}\to\varLambda^{+}_{c}D^{-}_{s}$ decays is measured to be \begin{equation*} \frac{\mathcal{B} ( \varLambda^{0}_{b}\to\varLambda^{+}_{c}K^{+}K^{-}\pi^{-}) } {\mathcal{B} ( \varLambda^{0}_{b}\to\varLambda^{+}_{c} D^{-}_{s})} = (9.26 \pm 0.29 \pm 0.46 \pm 0.26)\times10^{-2}, \end{equation*} where the first uncertainty is statistical, the second systematic and the third is due to the knowledge of the $D^{-}_{s}\to K^{+}K^{-}\pi^{-}$ branching fraction.

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. [...]

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.

Observation of $CP$ violation in two-body $B_{(\mathrm{s})}^{\,0}$-meson decays to charged pions and kaons / LHCb Collaboration
The time-dependent $CP$ asymmetries of $B^0\to \pi^+\pi^-$ and $B^0_\mathrm{s}\!\to K^+K^-$ decays are measured using a data sample of $pp$ collisions corresponding to an integrated luminosity of 1.9 fb$^{-1}$, collected with the LHCb detector at a centre-of-mass energy of 13 TeV. The results are \begin{eqnarray*} C_{\pi\pi} & = & -0.311 \pm 0.045 \pm 0.015, \newline S_{\pi\pi} & = & -0.706 \pm 0.042 \pm 0.013, \newline C_{KK} & = & \phantom{-}0.164 \pm 0.034 \pm 0.014, \newline S_{KK} & = & \phantom{-}0.123 \pm 0.034 \pm 0.015, \newline \cal {A}^{\Delta\Gamma}_{KK} & = & -0.83\phantom{0} \pm 0.05\phantom{0} \pm 0.09, \end{eqnarray*} where the first uncertainties are statistical and the second systematic.
