Title: Search for C P Violation and Measurement of the Branching Fraction in the Decay D0 K S 0 K S 0

Abstract

In this work we study the decay D 0 K S 0 K S 0 using 921 fb - 1 of data collected at or near the Υ(4S) and Υ(5S) resonances with the Belle detector at the KEKB asymmetric energy e+e- collider. The measured time-integrated CP asymmetry is A C P ( D 0 K S 0 K S 0 ) = ( - 0.02 ± 1.53 ± 0.02 ± 0.17 ) % , and the branching fraction is B ( D 0 K S 0 K S 0 ) = ( 1.321 ± 0.023 ± 0.036 ± 0.044 ) × 10 - 4 , where the first uncertainty is statistical, the second is systematic, and the third is due to the normalization mode ( D0 K S 0 π0 ). These results are furthermore more precise than previous measurements available for this mode. The A C P measurement is consistent with the standard model expectation.
