Abstract: (APS)

The mixings between exotic fermions in E6 27-plets (a Q=-(1/3) isosinglet quark h and charged and neutral leptons E and νE) and their familiar counterparts d, e, and νe are discussed and constraints from electroweak neutral-current data on such mixings are examined. We find off-diagonal couplings dh¯Z0, eĒZ0, and νeν¯EZ0 and propose new methods for single production of such new fermions in e+e− collisions and Z decay. Such couplings also lead (in general) to flavor-changing neutral currents and we examine constraints on the masses and mixings of the h quarks which can be derived from the K0-K¯0 system and KL→μ+μ−.
