Abstract

Using data from the FOCUS (E831) experiment, we have searched for T violation in charm meson decays using the four-body decay channels D ⁰→K^-K⁺π^-π⁺, D⁺→K_S⁰K⁺π ^-π⁺, and D_s⁺→K _S⁰K⁺π^-π⁺. The T violation asymmetry is obtained using triple-product correlations and assuming the validity of the CPT theorem. We find the asymmetry values to be A _Tviol(D⁰)=0.010±0.057(stat.)±0.037(syst.), A_Tviol(D⁺)=0.023±0.062(stat.)±0.022(syst.), and A_Tviol(D_s⁺)=-0.036±0.067(stat.) ±0.023(syst.). Each measurement is consistent with no T violation. New measurements of the CP asymmetries for some of these decay modes are also presented.
