A new technique to observe direct CP Violation in D mesons using Bose Symmetry and Dalitz Plot

Abstract

We present a new and sensitive method to observe direct CP violation in $D$ mesons using Bose symmetry and Dalitz plot. We apply the method to processes such as $B\to D^0{\bar{D}}^{0}P$, where $P$ is either a $K$ or a $\pi$. By choosing to reconstruct $D$ 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 $D^0{\bar{D}}^0$ in the final state. We briefly discuss how $B\to D^{\ast }{\bar{D}}^{\ast }P$ can also be used in a similar way.
