We have searched for the flavor-changing neutral current decays b {yields} X{mu}{sup +}{mu}{sup -} and B{sup 0} {yields} {mu}{sup +}{mu}{sup -} in p{anti p} collisions at {radical}s = 1.8 TeV with the D0 detector at Fermilab. Using our observed {mu}{sup +}{mu}{sup - } mass spectrum and the measured b production cross section we determine the 90% confidence limit for the branching fraction B(b {yields} s{mu}{sup +}{mu}{sup -}) < 3.6{times}10{sup -5}. For the exclusive, purely leptonic decay B{sup 0} {yields} {mu}{sup +}{mu}{sup -} we obtain a 90% confidence level limit B(B{sup 0} {yields} {mu}{sup +}{mu}{sup -}) < 8.0{times}10{sup -6}. 9 refs., 3 figs
