Abstract: (APS)
A search for a new charge -(1/3 quark has been carried out at the KEK e+e−Collider TRISTAN under the assumption of its photonic decay through a flavor-changing neutral current (FCNC). The observed number of multihadronic events with isolated photons is consistent with that expected from the known five quark flavors. Including the usual charged-current decays, limits on the absolute photonic branching ratio and FCNC processes were obtained.- ELECTRON POSITRON: COLLIDING BEAMS
