Abstract

We search for events in the Mark II detector at SLAC Linear Collider with the topology of a Z boson decaying into a pair of long-lived massive particles. No events that are consistent with the search hypothesis are found. Interpreting the long-lived particle as a sequential Dirac neutrino 4 of the fourth generation, we exclude at the 95% confidence level a significant range of mixing-matrix elements of 4 to other-generation neutrinos for a 4 mass from 10 to 43 GeV/c2. © 1990 The American Physical Society.
