摘要：

We have observed the rare decay K+ --> pi(+)mu(+)mu(-) and measured the branching ratio Gamma(K+ --> pi(+)mu(+)mu(-))/T(K+ --> all) = [5.0 +/- 0.4-(stat) +/- 0.7(syst) +/- 0.6(th)] x 10(-8). We compare this result with predictions from chiral perturbation theory and estimates based on the decay K+ --> pi(+)e(+)e(-).
