Measurement of the CKM angle $\gamma$ using the $B^{\pm}\rightarrow D^*h^{\pm}$ channels / LHCb Collaboration
A measurement of the $CP$-violating observables from $B^{\pm}\rightarrow D^* K^{\pm}$ and $\mbox{$B^{\pm}\rightarrow D^* \pi^{\pm}$}$ decays is presented, where $D^* (D) $ is an admixture of $D^{*0}$ and $\bar{D}^{*0}$ ($D^0$ and $\bar{D}^0$) states and is reconstructed through the decay chains $ D^* \rightarrow D\pi^0/\gamma$ and $\mbox{$D \to K_S^0 \pi^+\pi^-/K_S^0 K^+K^-$}$. The measurement is performed by analysing the signal yield variation across the $D$ decay phase space and is independent of any amplitude model. [...]

$\Lambda_c^+$ polarimetry using the dominant hadronic mode / LHCb Collaboration
The polarimeter vector field for multibody decays of a spin-half baryon is introduced as a generalisation of the baryon asymmetry parameters. Using a recent amplitude analysis of the $\Lambda_c^+ \to p K^- \pi^+$ decay performed at the LHCb experiment, we compute the distribution of the kinematic-dependent polarimeter vector for this process in the space of Mandelstam variables to express the polarised decay rate in a model-agnostic form.

Measurement of $\Upsilon$ production in $pp$ collisions at $\sqrt{s}$= 13 TeV / LHCb Collaboration
The production cross-sections of $\Upsilon(1S)$, $\Upsilon(2S)$ and $\Upsilon(3S)$ mesons in proton-proton collisions at $\sqrt{s}$= 13 TeV are measured with a data sample corresponding to an integrated luminosity of $277 \pm 11$ $\rm pb^{-1}$ recorded by the LHCb experiment in 2015. The $\Upsilon$ mesons are reconstructed in the decay mode $\Upsilon\to\mu^{+}\mu^{-}$. [...]

Search for CP violation using triple product asymmetries in $\Lambda^{0}_{b}\to pK^{-}\pi^{+}\pi^{-}$, $\Lambda^{0}_{b}\to pK^{-}K^{+}K^{-}$ and $\Xi^{0}_{b}\to pK^{-}K^{-}\pi^{+}$ decays / LHCb Collaboration
A search for $C$P and $P$ violation using triple-product asymmetries is performed with $\Lambda^{0}_{b}\to pK^{-}\pi^{+}\pi^{-}$, $\Lambda^{0}_{b}\to pK^{-}K^{+}K^{-}$ and $\Xi^{0}_{b}\to pK^{-}K^{-}\pi^{+}$ decays. The data sample corresponds to integrated luminosities of 1.0fb$^{-1}$ and 2.0fb$^{-1}$, recorded with the LHCb detector at centre-of-mass energies of 7TeV and 8TeV, respectively. [...]

First observation of the decay $B_{c}^{+}\to J/\psi K^+$ / LHCb collaboration
The decay $B_c^+\to J/\psi K^+$ is observed for the first time using a data sample, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb experiment in $pp$ collisions at a centre-of-mass energy of 7 TeV. A yield of 46$\pm12$ events is reported, with a significance of 5.0 standard deviations. [...]

Measurement of the $B^0 \to K^{*0}e^+e^-$ branching fraction at low dilepton mass / LHCb Collaboration
The branching fraction of the rate decay $B^0 \rightarrow K^{*0}e^+e^-$ in the dilepton mass region from 30 to 1000 MeV$/c^2$ has been measured by the LHCb experiment, using $pp$ collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, at a centre-of-mass energy of 7 TeV. The decay mode $B^0 \rightarrow J/\psi(e^+e^-) K^{*0}$ is utilized as a normalization channel. [...]

Measurement of the Drell-Yan cross section in pp collisions at √s = 7 TeV / CMS Collaboration
The Drell-Yan differential cross section is measured in pp collisions at sqrt(s) = 7 TeV, from a data sample collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 36 inverse picobarns. The cross section measurement, normalized to the measured cross section in the Z region, is reported for both the dimuon and dielectron channels in the dilepton invariant mass range 15-600 GeV. [...]
