Analysis of the anomalous events $e^{+}{e}^{-}\to l^{+}{\text{l}}^{-}\gamma \gamma$

Abstract

The $e^{+}{e}^{-}\to l^{+}{\text{l}}^{-}\gamma \gamma$ anomalous events, regis\-te\-red at $L3$ de\-tec\-tor at $e^{+}{e}^{-}$ $CERN-LEP$ collider have been analysed. It has been shown that the interpretation of such events as a manifestation of scalar (pseudoscalar) resonance with the mass of 60 GeV contradicts other experimental data.
