XXXV. Measurements of the lifetimes of charged heavy unstable particles

A new counter method for measuring the lifetime of unstable mesons is described. Lifetime measurements on 13 charged heavy mesons are reported. It is concluded that if there exists only one heavy meson giving fast decay products, with a lifetime greater than 5 × 10 -9 sec, its lifetime is sec. No ev...

Zusammenfassung:A new counter method for measuring the lifetime of unstable mesons is described. Lifetime measurements on 13 charged heavy mesons are reported. It is concluded that if there exists only one heavy meson giving fast decay products, with a lifetime greater than 5 × 10 -9 sec, its lifetime is sec. No evidence for any longer-lived heavy mesons has been found.
