An E$_6$ interpretation of an $e^+ e^- \gamma \gamma E\!\!\!/_T$ event
The lowest-dimensional representation of the group E$_6$ contains both the standard quarks and leptons and a set of exotic quarks and leptons whose decays can involve a series of chains ending in radiative decay of one light neutrino species to another. The possibility is explored that such a chain...
