The $e^{+}\,e^{-}\,\rightarrow\,l^{+}\, ł^{-}\,γ\,γ$ 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.
The hypothetic R--resonance production (anomalous "$l\bar lγγ$" events at LEP) with 60 GeV mass at FNAL hadron collider has been considered. The cross-section of this R-resonance production with the consequent decay $R \to γγ$ is obtained. Various distributions of leptons and photons in the process $p\bar p \to l\bar l R (\to γγ) X$ are calculated.
The $e^{+}\,e^{-}\,\rightarrow\,l^{+}\, ł^{-}\,γ\,γ$ 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.
The $B_c$--meson production cross section was calculated in the perturbative QCD. Various distributions of the charged leptons from the $B_c \to l νJ/ψ(\to l^+ l^-)$ decay were obtained. The $B_c$--meson mass measurement from such decays is also discussed.
In this paper we summarize the results of the theory working group dedicated to the analysis of $B_c$ production at hadron colliders.
