Abstract
We have searched for the decay D-0 --> mu(+)mu(-) among 1.25 x 10(5) m u(+)mu(-) pairs produced by 350 GeV/c pi(-) particles interacting in c opper and tungsten targets. Using a high-resolution silicon-microstrip detector followed by a large-acceptance magnetic spectrometer and a m uon filter we are able to discriminate between prompt and non-prompt m uons and to measure dimuon masses. No candidate compatible with a D-0 --> mu(+)mu(-) decay has been found, allowing us to set an upper limit on the branching fraction B(D-0 --> mu(+)mu(-)) of 7.6 x 10(-6) at th e 90% confidence level.
