In deep inelastic interactions of 200 GeV muons with a carbon target, we have found 17 events of the type μ±N→μ±μμX ("wrong-sign" dimuons). We derive upper limits of 1.2% (90% CL) on D0-D0 transitions (mixing) or, alternatively, of 9 pb (90% CL) cross section for BB pair production as possible sources of such events.
