Abstract
The LHCb detector is a single-arm forward spectrometer that collects data at the LHC, designed for studies of flavour physics with high precision. We present a selection of recent measurements of mixing and CP-violating parameters, including sin 2β and weak phase ϕ s, using several decays. A good understanding of the pollution from sub-leading penguin to pologies in these measurements can be achieved by measuring CP violation and polarization in the decay Bs0→Jψ⁄K0* and B0→Jψ⁄ ρ0. All results here presented are obtained using the full Run I dataset.
Highlights
Studies of CP violation with heavy-flavoured hadrons are amongst the main interests of the LHCb collaboration
They can unveil indirect evidence of New Physics, revealing inconsistencies with respect to theoretical predictions based on the validity of the Standard Model (SM)
In the analyses presented below, the decay time distribution was extensively modeled taking into account different detector conditions using real and Monte Carlo data samples
Summary
Studies of CP violation with heavy-flavoured hadrons are amongst the main interests of the LHCb collaboration. In this summary, selected results regarding B mesons mixing and CP violation are presented, including the measurements of the weak phases φd and φs and measurements to constrain penguin pollution.
