Abstract

We have measured B0B0 mixing by observing like-sign dilepton events in (4S) decay. Assuming that the semileptonic branching fractions of the charged and neutral B mesons are equal and that the (4S) decays to B+B- 55% of the time and to B0B0 45% of the time, we measure the mixing parameter r to be 0.190.060.06, where the first error is statistical and the second is systematic.
