B+ &rarr &mu+&mu&minusK+,
B0 &rarr &mu+&mu&minusK*0, and
Bs &rarr &mu+&mu&minus&phi .
This web page summarizes the measurement of rare flavor-changing neutral current
B meson decays with two muons in the final state, based
based upon 924 pb&minus 1 of CDF II data.
The results have been approved as of November 30, 2006.
B(B+ &rarr &mu+&mu&minusK+) =
(0.60 ± 0.15 ± 0.04)×10-6,
