Study of high-mass photon pairs in $e^{+}e^{-}\gamma\gamma$ events
From the analysis of the reactions $e^{+} e^{-} \to e^{+} e^{-} + (n\gamma s) (1=e,\nu,\tau)$ we observe four events, one $e^{+} e^{-} \gamma\gamma$and three $\mu^{+} \mu^{-} \gamma\gamma$, with the invariant mass of the photon pairs close to 60 $GeV/c^{2}$. These events were selected from a datasam...

| description | From the analysis of the reactions $e^{+} e^{-} \to e^{+} e^{-} + (n\gamma s) (1=e,\nu,\tau)$ we observe four events, one $e^{+} e^{-} \gamma\gamma$and three $\mu^{+} \mu^{-} \gamma\gamma$, with the invariant mass of the photon pairs close to 60 $GeV/c^{2}$. These events were selected from a datasample collected in the L3 detector corresponding to 950,000 produced $Z^{0}'s$. The detailed distribution of these events and their possible origin will be presented. |
