The possibility of the production of long-lived anomalous particles (APs), particles with anomalously short mean free paths, is explored in 147-GeV/c +p, K+p, and pp interactions. Limits are set on AP production using the noninteracting particles produced in these hadron-proton collisions and using published interaction cross sections to define nonanomalous behavior. The three-standard-deviation upper limits on the fraction of produced particles that may be considered APs decrease from less than 3% at an AP-proton cross section of 150 mb to less than 0.1% at an AP-proton cross section of 3 b.
