Abstract

A search for a fourth-generation quark with -Q-=e/3 has been made with the VENUS detector at the KEK e+e- collider TRISTAN. Multihadron events with a spherical shape or containing isolated leptons were studied. There is no evidence for an excess production of such events in e+e- collision at s =56"57 GeV and a lower limit on the mass is 27.5 GeV/c2 at the 95% C.L.
