Detection of Short-Lived Particles in Nuclear Emulsions

摘要

We present a method for detecting short-lived particles in nuclear emulsions. Production and decay vertices as close as 0.5 mu m can resolved. This corresponds to a lifetime of the order of 10- exp 15 s. The principle is to fit straight lines to the tracks and make a chi-square test of the hypothesis of a single vertex. This technique may be useful for detecting decays of heavy quarks. (Atomindex citation 11:511434)
