摘要：

Evidence of physics beyond the Standard Model (SM) of particle physics might be revealed through CP violation. Experimental results from BaBar, Belle, and most recently from Large Hadron Collider b-factory (LHCb) are very interesting in this respect. Calculating various CP violation parameters within the SM is reported. In this letter, the final state interaction (FSI) phases with the CKM matrix are calculated by using the recent experimental results from LHCb on CP violation in and meson decays. To obtain the allowed regions of the FSI phases, we used a simplified form of the Jarlskog determinant of the CKM matrix, and we found the CP phase delta close to the maximal phase of pi/2. Then, the asymmetry data on and from LHCb were used to explore graphically the allowed regions of the FSI phases.
