First measurement of Zμ+μ angular coefficients in the forward region of pp collisions at s=13 TeV / LHCb Collaboration
The first study of the angular distribution of μ+μ pairs produced in the forward rapidity region via the Drell-Yan reaction ppγ/Z+Xl+l+X is presented, using data collected with the LHCb detector at a centre-of-mass energy of 13TeV, corresponding to an integrated luminosity of 5.1 fb1. The coefficients of the five leading terms in the angular distribution are determined as a function of the dimuon transverse momentum and rapidity. [...]

Measurement of τL using the Bs0J/ψη decay mode / LHCb Collaboration
Using a proton-proton collision data sample collected by the LHCb detector and corresponding to an integrated luminosity of 5.7 fb1, the lifetime of the Bs0 mass eigenstate, τL, is measured using Bs0J/ψη decay mode to be τL = 1.445 ± 0.016(stat) ± 0.008(syst) ps. A combination of this result with a previous LHCb analysis using an independent dataset corresponding to 3 fb1 of integrated luminosity gives τL = 1.452 ± 0.014 ± 0.007 ± 0.002 ps, where the first uncertainty is statistical, the second due to the uncorrelated part of the systematic uncertainty and the third due to the correlated part of the systematic uncertainty..

Search for massive long-lived particles decaying semileptonically at s=13 TeV / LHCb Collaboration
A search is performed for massive long-lived particles (LLP) decaying semileptonically into a muon and two quarks. Two kinds of LLP production processes were considered. [...]

Measurement of J/ψ production cross-sections in pp collisions at s=5 TeV / LHCb Collaboration
The production cross-sections of J/ψ mesons in proton-proton collisions at a centre-of-mass energy of s=5 TeV are measured using a data sample corresponding to an integrated luminosity of 9.13±0.18 pb1, collected by the LHCb experiment. The cross-sections are measured differentially as a function of transverse momentum, pT, and rapidity, y, and separately for J/ψ mesons produced promptly and from beauty hadron decays (nonprompt).

First measurement of the CP-violating phase in Bs0J/ψ(e+e)ϕ decays / LHCb Collaboration
A flavour-tagged time-dependent angular analysis of Bs0J/ψϕ decays is presented where the J/ψ 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 fb1. [...]

Precise determination of the Bs0B¯s0 oscillation frequency / LHCb Collaboration
 Mesons comprising a beauty quark and a strange quark can oscillate between particle (B0s) and antiparticle (B0sbar) flavour eigenstates, with a frequency given by the mass difference between heavy and light mass eigenstates, deltams. Here we present a measurement of deltams using B0s2DsPi decays produced in proton-proton collisions collected with the LHCb detector at the Large Hadron Collider. [...]

Search for long-lived particles decaying to e±μν / LHCb Collaboration
Long-lived particles decaying to e±μν, with masses between 7 and 50 GeV/c2 and lifetimes between 2 and 50 ps, are searched for by looking at displaced vertices containing electrons and muons of opposite charges.
