Description

As a by-product to the study of muon pairs produced by 255-GeV/c pions, data from Fermilab yield upper limits on the decay D0→μ+μ- and on D0-D-bar0 mixing. An unrestricted sample of 122 630 unlike-sign muon pairs allows a 90%-C.L. (confidence level) upper limit of 1.1 x 10-5 to be placed on the branching ratio of the charm-changing neutral-current decay D0→μ+μ-. From a sample of 3973 like-sign muon pairs, the ratio r = GAMMA(D-bar0→μ+X)/GAMMA(D0→μ -x) is determined to be r<5.6 x 10-3 at 90% C.L
