Abstract

We present a new and sensitive method to observe direct CP violation in DD mesons using Bose symmetry and Dalitz plot. We apply the method to processes such as BD0Dˉ0PB \to D^0\bar{D}^0 P, where PP is either a KK or a π\pi. By choosing to reconstruct DD mesons only through their decays into CP eigenstates, we show that any asymmetry in the Dalitz plot can arise only through direct CP violation. We further show how CP violation parameters can be determined. Since the approach involves only Bose symmetry, the method is applicable to any multi-body process that involves D0Dˉ0D^0\bar{D}^0 in the final state. We briefly discuss how BDDˉPB\to D^* \bar{D}^* P can also be used in a similar way.
