The LHCb experiment is planning to operate with a 7.5-fold increase in instantaneous luminosity for LHC Runs 5 and 6. The performance of the Vertex Locator detector is crucial in the event reconstruction at the increased pile-up, providing real-time information to be used in the trigger. [...]

Model-independent confirmation of the Z(4430)Z(4430) state / LHCb collaboration
The decay B0ψ(2S)K+πB0ψ(2S)K+π is analyzed using 3 fb13 fb1 of pppp collision data collected with the LHCb detector. A model-independent description of the ψ(2S)πψ(2S)π mass spectrum is obtained, using as input the KπKπ mass spectrum and angular distribution derived directly from data, without requiring a theoretical description of resonance shapes or their interference.

Measurement of the CP-violating phase ϕsϕs in ˉB0sD+sDs¯B0sD+sDs decays / LHCb collaboration
We present a measurement of the CPCP-violating weak mixing phase ϕsϕs using the decay ˉB0sD+sDs¯B0sD+sDs in a data sample corresponding to 3.03.0 fb11 of integrated luminosity collected with the LHCb detector in pppp collisions at centre-of-mass energies of 7 and 8 TeV. An analysis of the time evolution of the system, which does not constrain |λ|=1|λ|=1 to allow for the presence of CPCP violation in decay, yields ϕs=0.02±0.17ϕs=0.02±0.17 (stat) ±0.02±0.02 (syst) rad, |λ|=0.91+0.180.15|λ|=0.91+0.180.15 (stat) ±0.02±0.02 (syst).

Measurement of the ηc(1S)ηc(1S) production cross-section in proton-proton collisions via the decay ηc(1S)pˉpηc(1S)p¯p / LHCb collaboration
The production of the ηc(1S)ηc(1S) state in proton-proton collisions is probed via its decay to the pˉpp¯p final state with the LHCb detector, in the rapidity range 2.0<y<4.52.0<y<4.5 and in the meson transverse-momentum range pT>6.5pT>6.5 GeV/c. The cross-section for prompt production of ηc(1S)ηc(1S) mesons relative to the prompt J/ψJ/ψ cross-section is measured, for the first time, to be σηc(1S)/σJ/ψ=1.74±0.29±0.28±0.18Bσηc(1S)/σJ/ψ=1.74±0.29±0.28±0.18B at a centre-of-mass energy s=7s=7 TeV using data corresponding to an integrated luminosity of 0.7 fb11, and σηc(1S)/σJ/ψ=1.60±0.29±0.25±0.17Bσηc(1S)/σJ/ψ=1.60±0.29±0.25±0.17B at s=8s=8 TeV using 2.0 fb11.

Determination of γγ and 2βs2βs from charmless two-body decays of beauty mesons / LHCb collaboration
Using the latest LHCb measurements of time-dependent CPCP violation in the B0sK+KB0sK+K decay, a U-spin relation between the decay amplitudes of B0sK+KB0sK+K and B0π+πB0π+π decay processes allows constraints to be placed on the angle γγ of the unitarity triangle and on the B0sB0s mixing phase 2βs2βs. Results from an extended approach, which uses additional inputs on B0π0π0B0π0π0 and B+π+π0B+π+π0 decays from other experiments and exploits isospin symmetry, are also presented. [...]
