Title: Search for the decays B{sub d}{sup 0}{r_arrow}{mu}{sup +}{mu}{sup {minus}} and B{sub s}{sup 0}{r_arrow}{mu}{sup +}{mu}{sup {minus}} in p{bar p} collisions at {radical} (s) =1.8 TeV

Search for the decays B{sub d}{sup 0}{r_arrow}{mu}{sup +}{mu}{sup {minus}} and B{sub s}{sup 0}{r_arrow}{mu}{sup +}{mu}{sup {minus}} in p{bar p} collisions at {radical} (s) =1.8 TeV We present a search for the flavor-changing neutral current decays B{sub d}{sup 0}{r_arrow}{mu}{sup +}{mu}{sup {minus}} and B{sub s}{sup 0}{r_arrow}{mu}{sup +}{mu}{sup {minus}} in p{bar p} collisions at {radical} (s) =1.8TeV, using 98pb{sup {minus}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{sub d}{sup 0}{r_arrow}{mu}{sup +}{mu}{sup {minus}}){lt}8.6{times}10{sup {minus}7} and B(B{sub s}{sup 0}{r_arrow}{mu}{sup +}{mu}{sup {minus}}){lt}2.6{times}10{sup {minus}6} at 95{percent} confidence level. {copyright} {ital 1998} {ital The American Physical Society}
