Abstract
We investigate the question of whether an additional light neutral sca lar can explain the l+l-gammagamma events with high invariant mass pho ton pairs recently observed by the L3 Collaboration. We parameterize t he low energy effects of the unknown dynamics in terms of higher dimen sional effective operators. We show that operators which allow for the scalar to be produced and decay into photon pairs will allow other ob servable processes that should have been seen in current experiments.
