CP Asymmetry In Neutral $B$ System At Symmetric Colliders

Abstract

Contrary to the conventional belief, time integrated asymmetry are measurable in selected final states in the neutral $B$ system at symmetric $e^{+}{e}^{-}$ colliders. They occur due to the interplay of weak and strong phases of two different amplitudes in addition to the $B^0-{\bar{B}}^0$ mixing. Observation of these asymmetries would be evidence for direct CP violation in the decay amplitudes.
