Abstract
Abstract
We search for CP violation in the decay
${D^{+}}\to K_S^0{K^{+}}$
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
${D^{+}}\to K_S^0{K^{+}}$
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
${K^0}-{{\overline{K}}^0}$
mixing, the CP asymmetry in
${D^{+}}\to {{\overline{K}}^0}{K^{+}}$
decay is found to be (+0.08 ± 0.28 ± 0.14)%.
