摘要：

A search for the decay pi-0 --> gamma-X, where X is any long-lived weakly interacting neutral vector particle with mass smaller than the neutral pion mass, was performed using neutral pions tagged by K+ --> pi+pi-0 A 90%-C.L. upper limit for the branching ratio of the two-body decay B(pi-0 --> gamma-X) < 5 x 10(-4) is set. Limits are also set for three-body decays pi-0 --> gamma-XX'.
