Gauge Kinetic Mixing and Leptophobic Z ′ in E 6 and SO ( 10 )

We examine the influence of gauge kinetic mixing on the couplings of a TeV scale Z ′ in both E6 and SO(10) models. The strength of such mixing, which arises due to the existence of incomplete matter representations at low scale, can be described by a single parameter, δ. The value of this parameter can significantly influence the ability of both hadron and… CONTINUE READING
