Observation of CP violation in B-meson decays
With this review, Physics–Uspekhi continues to discuss one of the most mysterious phenomenon in particle physics, that of CP violation. Recent research in this area has focused especially on the properties of B mesons. Successful B-factory experiments have allowed both the detection and detailed study of CP violation in B-meson decays. Presented here is a state of the art review of the field.

Upgrade of the KEDR tagging system
An upgrade of a special system to tag scattered electrons from two-photon processes, based on triple-GEM detectors, is described. The system is intended for the experiments at the VEPP-4M storage ring. Tests of the detector prototype with two gas mixtures confirm the feasibility of the chosen upgrade layout.

Study of a model-independent method for the measurement of the angle phi_3
This report shows the latest results on the study of the method to determine the angle phi_3 of the unitarity triangle using Dalitz plot analysis of $D^0$ decay from B->DK process in a model-independent way. We concentrate on the case with a limited charm data sample, which will be available from the CLEO-c collaboration in the nearest future, with the main goal to find the optimal strategy for phi_3 extraction. We find that the analysis using decays of D_CP only cannot provide a completely model-independent measurement in the case of limited data sample. The procedure involving binned analysis of B->DK and psi(3770)->(K^0_S pi^+ pi^-)_D(K^0_S pi^+ pi^-)_D decays is proposed, that allows to obtain the phi_3 precision comparable to unbinned model-dependent fit.
