Abstracts
The rate of like-charge dimuons has been measured with the MAC detector in hadronic events produced in e+ e annihilation at = 29 GeV. If the observed excess is attributed to Bo-o mixing, the corresponding value of the mixing parameter = (B - X)/(B X) is = 0.21+0.29-0.15 and > 0.02 at 90% CL.
