We report on a search for the flavor-changing neutral current decays B+-->mu(+)mu(-)K(+) and B-0 --> mu(+)mu(-) K-*0 using 88 pb(-1) of data from (p) over bar p collisions at root s = 1.8 TeV, collected with the Collider Detector at Fermilab. Finding no evidence for these decays, we set upper limits on the branching fractions B(B+ -->mu(+)mu(-)K(+)) < 5.2 x 10(-6) and B(B-0 --> mu(+) mu(-) K-*0) < 4.0 x 10(-6) at the 90% confidence level.

Abstract
We report on a search for the flavor-changing neutral current decays B+-->mu(+)mu(-)K(+) and B-0 --> mu(+)mu(-) K-*0 using 88 pb(-1) of data from (p) over bar p collisions at root s = 1.8 TeV, collected with the Collider Detector at Fermilab. Finding no evidence for these decays, we set upper limits on the branching fractions B(B+ -->mu(+)mu(-)K(+)) < 5.2 x 10(-6) and B(B-0 --> mu(+) mu(-) K-*0) < 4.0 x 10(-6) at the 90% confidence level.File in questo prodotto:
