“…Intensive studies of CP violation, especially at the e + e − B factories (see e.g. (Bevan et al, 2014) for a comprehensive review), provide convincing evidence that the main source of CP violation is the phase in the CKM matrix. More precisely, a vast body of measurements performed in different experimental conditions, such as accelerators, energies of operation, and detectors, confirm the unitarity of the CKM matrix, see (Amhis et al, 2014).…”
