Description

Works, according to the Specification for the agreement "CP symmetry in rare decay modes of heavy mesons at the LHCb experiment", were fully done. CP violation phenomena in the neutral Bs meson decay to the final state with J/psi meson (decay into 2 muons) and phi meson (decay into 2 kaons) was researched, namely, CP violating phase (phi_s) was measured with most precisely accuracy up to date and it is -10+/-39 mrad. These measurements are in agreement with Standard Model prediction. Also, in frame of current work, installation and setting of the LHCb Radiation Monitoring System was done.5481
