Preliminary results on B0-anti B0 mixing from MAC

Creators

Description

An excess of like-charge dimuons has been observed with the MAC detector in multihadron events produced in e+e- annihilation at √s = 29 GeV. If this excess is attributed to B0 - anti B0 mixing, the corresponding value of the mixing parameter chi = Γ(B → μ-X)/Γ(B → μ+-X) is chi = 0.21/sub -0.15//sup +0.25/ and chi > 0.02 at 90% C.L
