Description

Models with heavy (approx.= msub(Z)) spinless boson production and its subsequent radiative decay into a lepton pair and a photon are studied, with cuts appropriate to the CERN panti p collider experiments. Dalitz plots for the l+l-γ final state and their projections are shown; the agreement with the data is generally slightly better than the radiative Z decay models but is not sufficient to account for the characteristics of the three observed events.
