Z' Bosons from E(6): Collider and Electroweak Constraints
Jens Erler, Paul Langacker, Shoaib Munir, Eduardo Rojas · arXiv (Cornell University) · 2011
Many models beyond the Standard Electroweak Theory, top-down or bottom-up, contain extensions of the gauge symmetry group by extra U(1)' factors which can be understood or treated as subgroups of E(6). A brief overview of such models is followed by a sketch of a systematic classification. We then describe how the resulting extra massive neutral gauge bosons can be searched for and in case of positive evidence diagnosed using electroweak and collider data.
