Search for flavor-changing neutral current B meson decays in pp̄ collisions √s = 1.8 Te V

We report on a search for the flavor-changing neutral current decays B{sub d,s}{sup 0}{yields}{mu}{sup +}{mu}{sup -}, B{sup +}{yields}{mu}{sup +}{mu}{sup -}K{sup +}, and B{sup 0}{yields}{mu}{sup +}{mu}{sup -}K*{sup 0} using data from p{bar p} collisions at {radical}s= 1.8 TeV, collected with the Collider Detector at Fermilab during the 1992-1993 running period. We find no indication of such decays and we set the following 90% confidence level upper limits on branching ratios: B(B{sup 0}{yields}{mu}{sup +}{mu}{sup -})<1.6x10{sup -6}, B(B{sub s}{sup 0}{yields}{mu}{sup +}{mu}{sup -})<8.4 x 10{sup -6}, B(B{sup +}{yields}{mu}{sup +}{mu}{sup -}K{sup +})<1.0x10{sup -5}, and B(B{sup 0}{yields}{mu}{sup +}{mu}{sup -}K*{sup 0})<2.5x10{sup -5}.
