Search for D{sup +} {yields} {pi}{sup +}{mu}{sup +}{mu}{sup {minus}}
Flavor-changing neutral current decays are forbidden in lowest order in the Standard Model. The authors present results of a search for the charm changing neutral current decay D{sup +} {yields} {pi}{sup +}{mu}{sup +}{mu}{sup {minus}} based on the analysis of one third of the data from Fermilab experiment E791, accumulated during the 1991--92 fixed target run with a 500 GeV negative pion beam incident on a segmented target. Assuming that the decay kinematics are the same as for D{sup +} {yields} K{sup {minus}}{pi}{sup +}{pi}{sup +}, they set an upper limit on the branching ratio for this channel, B(D{sup +} {yields} {pi}{sup +}{mu}{sup +}{mu}{sup {minus}}) < 4.6 {times} 10{sup {minus}5} at the 90% confidence level.
