A closer look at the possible CMS signal of a new gauge boson

Abstract

The CMS collaboration has recently reported a 2.8$\sigma$ excess of $eejj$ events with an invariant mass around 2 TeV. This observation can be explained in the context of standard model extensions with new gauge bosons $W^{\prime }$, $Z^{\prime }$ and heavy neutrinos coupling (mainly) to the electron. We discuss additional signals that allow to confirm or discard the $W^{\prime }$ and $Z^{\prime }$ hypotheses.
