Extra neutral gauge bosons and Higgs bosons in an E_6-based model

Abstract

Extra neutral gauge bosons and Higgs bosons in an effective low-energy $SU(2{)}_L\times SU(2{)}_I\times U(1{)}_Y\times U(1{)}_{Y^{\prime }}$ model, which is a subgroup of $E_6$, are studied. $SU(2{)}_I$ is a subgroup of $SU(3{)}_R$ and commutes with the electric charge operator, so the three corresponding gauge bosons are neutral. Electroweak precision experiments are used to put constraints on masses of the extra neutral gauge bosons and on the mixings between them and the ordinary Z boson, including constraints arising from a proposed measurment of the weak charge of the proton at Jefferson Lab. Bounds on and relationships of masses of Higgs bosons in the supersymmetric version of the model are also discussed.
