Measurement of the y_CP parameter in D^0 decays to K+K-K_S final state, dominated by the intermediate resonant contribution Phi K_S. The y_CP parameter coincides with the parameter y in the limit of negligible CP violation. The latter parameter describes the decay width difference of two neutral D meson mass eigenstates (these do not coincide with the so called flavour eigenstates - D0 and anti-D0; this fact is a condition for the mixing and CP violation phenomena to appear). The result agrees with the current world average of the y measurements and will reduce the uncertainty of the latter.
