Effects of Possible $ΔB =- ΔQ$ Transitions in Neutral $B$ Meson Decays}

Abstract

We explore the possibility that the existing data on like-sign dileptons at the $Υ(4S)$ resonance consist of events arising from $B_{d}^0 -\bar B_{d}^0$ mixing and also from $ΔB = - ΔQ$ transitions. The consequences of these nonstandard transitions for certain time-asymmetries which are likely to be measured at the $B$ factories are studied.
