Abstract
We consider the 4 γγll (l = μ, e) events reported by the L3 collaboration, and go through the logical possibilities which could explain the events. If they are not coincidental bremsstrahlung events, we find that the kinds of physics which they could point to are extremely limited. One must have a new boson (X0) of mass 60 GeV with a branching ratio to γγ of order one. An additional particle with exotic couplings would also be required. If this new particle were spin 1, it would have couplings which are non-perturbative. If it were spin 0, it would have to have couplings which are not proportional to mass. Our goal is not to propose specific models, but rather to chart the kinds of models which would need to be considered should the L3 events prove to be new physics.
