Abstract
We present a search for the flavor-changing neutral current decays B-d(0)-->mu(+)mu(-) and B-s(0)-->mu(+)mu(-) in <p(p)over bar> collisions at root s=1.8 TeV, using 98 pb(-1) of data collected at the Collider Detector at Fermilab. We find one candidate event for these decays, which is consistent with the background estimates, and set upper limits on the branching fractions of B(B-d(0)-->mu(+)mu(-))<8.6X10(-7) and B(B-s(0)-->mu(+)mu(-))<2.6X10(-6) at 95% confidence level. [S0556-2821(98)50207-X].
