Abstract
We report on a search for B(s)(0)-->mu(+)mu(-) and B(d)(0)-->mu(+)mu(-) decays in p (p) over bar collisions at roots=1.96 TeV using 171 pb(-1) of data collected by the CDF II experiment at the Fermilab Tevatron Collider. The decay rates of these rare processes are sensitive to contributions from physics beyond the standard model. One event survives all our selection requirements, consistent with the background expectation. We derive branching ratio limits of B(B(s)(0)-->mu(+)mu(-))<5.8x10(-7) and B(B(d)(0)-->mu(+)mu(-))<1.5x10(-7) at 90% confidence level.
