  The $e^{+}\,e^{-}\,\rightarrow\,l^{+}\, \l^{-}\,\gamma\,\gamma$ anomalous
events, detected by $L3$ 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. In case of a possible existence that kind
of resonance, the perspectives to discover one in some processes at future
$e^+e^-$ colliders have been discussed.
