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. [...]

Spectroscopy in Beauty Decays at the LHCb Experiment / LHCb Collaboration
The beauty hadron decays is unique laboratory to study charmonium and charmonium-like states, such as the χc1(3872) meson, other exotic states and the tensor D-wave Ψ2(3823) states. However the nature of many exotic charmonium-like candidates are still unknown. [...]

Observation of the Bs0D±D decay / LHCb Collaboration
A search for the Bs0D±D decay is performed using proton-proton collision data at centre-of-mass energies of 7, 8 and 13TeV collected by the LHCb experiment, corresponding to an integrated luminosity of 9fb1. The decay is observed with a high significance and its branching fraction relative to the B0D±D decay is measured to be B(Bs0D±D)B(B0D±D)=0.137±0.017±0.002±0.006, where the first uncertainty is statistical, the second systematic and the third is due to the uncertainty on the ratio of the Bs0 and B0 hadronisation fractions..

Observation of CP violation in two-body B(s)0-meson decays to charged pions and kaons / LHCb Collaboration
The time-dependent CP asymmetries of B0π+π and Bs0K+K decays are measured using a data sample of pp collisions corresponding to an integrated luminosity of 1.9 fb1, collected with the LHCb detector at a centre-of-mass energy of 13 TeV.

First observation of the decay Bs0Kμ+νμ and measurement of |Vub|/|Vcb| / LHCb Collaboration
The first observation of the suppressed semileptonic Bs0Kμ+νμ decay is reported. Using a data sample recorded in pp collisions in 2012 with the LHCb detector, corresponding to an integrated luminosity of 2 fb1, the branching fraction B(Bs0Kμ+νμ)} is measured to be (1.06±0.05 (stat)±0.08 (syst))×104, where the first uncertainty is statistical and the second one represents the combined systematic uncertainties.

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. The search is performed using 5.4 fb1 of pp collisions collected with the LHCb detector at a centre-of-mass energy of s=13 TeV. [...]

Measurement of the CKM angle γ and Bs0Bs0¯ mixing frequency with Bs0Dsh±π±π decays / LHCb Collaboration
The CKM angle γ is measured for the first time from mixing-induced CP violation between Bs0DsK±π±π and B¯s0Ds±Kππ± decays reconstructed in proton-proton collision data corresponding to an integrated luminosity of 9 fb1 recorded with the LHCb detector. A time-dependent amplitude analysis is performed to extract the CP-violating weak phase γ2βs and, subsequently, γ by taking the Bs0-B¯s0 mixing phase βs as an external input. [...]
