Abstract

A search for sequential heavy leptons has been performed at the center-of-mass energy of 52 GeV at the KEK colliding-beam accelerator TRISTAN. We have found no evidence for the production of heavy leptons with the integrated luminosity of 2.9 pb-1. A lower mass limit of 25.0 GeV/c2 at 95% confidence level was obtained.
