摘要：

A search for lepton flavor violating decays, K+ --> mu(+)mu(+)pi(-), K+ --> pi(+)e(+)mu(-), K+ --> mu(+)e(+)pi(-), was performed using the data collected in Experiment E865 at the Brookhaven Alternating Gradient Synchrotron. No signal was found in any of the decay modes. At the 90% confidence level, the branching ratios are less than 3.0 X 10(-9), 6.4 X 10(-10), 5.2 X 10(-10) 5.0 x 10(-10), and 3.4 X 10(-9), respectively.
