We have performed a search for B(s)(0)->mu(+)mu(-) and B(0)->mu(+)mu(-) decays in p (p) over bar collisions at root s = 1.96 TeV using 2 fb(-1) of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron Collider. The observed number of B(s)(0) and B(0) candidates is consistent with background expectations. The resulting upper limits on the branching fractions are B(B(s)(0)->mu(+)mu(-))< 5.8x10(-8) and B(B(0)->mu(+)mu(-)) < 1.8 x 10(-8) at 95% C.L.

Abstract
We have performed a search for B(s)(0)->mu(+)mu(-) and B(0)->mu(+)mu(-) decays in p (p) over bar collisions at root s = 1.96 TeV using 2 fb(-1) of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron Collider. The observed number of B(s)(0) and B(0) candidates is consistent with background expectations. The resulting upper limits on the branching fractions are B(B(s)(0)->mu(+)mu(-))< 5.8x10(-8) and B(B(0)->mu(+)mu(-)) < 1.8 x 10(-8) at 95% C.L.File in questo prodotto:
