In a previous publication we noted that the time dependence of an incoherent B{sup 0}-B{sup 0} mixture undergoes a qualitative change when the magnitude of CP violation {delta} exceeds a critical value. Requiring, on physical grounds, that the system evolve from an initial incoherent state to a final pure state in a monotonic way yields a new upper limit for {delta}. The recent measurement of the wrong charge semileptonic asymmetry of B{sub s}{sup 0} mesons presented by the D0 collaboration is outside this bound by 1 standard deviation. If this result is confirmed it implies the existence of a new quantum mechanical oscillation phenomenon.
