| Research Abstract |
We report a measurement of CP violation asymmetries in B^0→K^+K^-Ks decays with a time-dependent Dalitz approach. B^0→K^+K^-Ks decay channels consist of several intermediate stats. It is expected that the sensitivity to CP violating parameters would improve in a measurement using the time-dependent Dalitz plot distribution because of the correct treatment of interferences between various resonant and non-resonant process.
