Abstract: (arXiv)
The CDF and D0 data of nearly 475 pb1\text{pb}^{-1} in the dilepton channel is used to probe a recent class of models, Stueckelberg extensions of the Standard Model (StSM), which predict a ZZ' boson whose mass is of topological origin with a very narrow decay width. A Drell-Yan analysis for dilepton production via this ZZ' shows that the current data put constraints on the parameter space of the StSM. With a total integrated luminosity of 88 fb1\text{fb}^{-1}, the very narrow ZZ' can be discovered up to a mass of about 600 GeV. The StSM ZZ' will be very distinct since it can occur in the region where a Randall-Sundrum graviton is excluded.
