Abstract

A bstract We search for CP violation in the decay D⁺→ K_S⁰K⁺ using a data sample with an integrated luminosity of 977 fb −1 collected with the Belle detector at the KEKB e + e − asymmetric-energy collider. No CP violation has been observed and the CP asymmetry in D⁺→ K_S⁰K⁺ decay is measured to be (−0.25 ± 0.28 ± 0.14)%, which is the most sensitive measurement to date. After subtracting CP violation due to K⁰-K⁰ mixing, the CP asymmetry in D⁺→ K⁰K⁺ decay is found to be (+0.08 ± 0.28 ± 0.14)%.
