Associated Production of $H^0γ$ or $H^0Z^0$ pairs at $μ^+μ^-$ Collisions

We calculate the cross-sections for the production of Standard Model Higgs Boson in association with the neutral gauge bosons (photon and Z--boson). For the case of reaction $μ^+ μ^- \to γH^0$, complete and compact analytical expressions for the differential and total cross--sections, applicable also for the case of any (pseudo)scalar particle with mass-coupling proportionality, in particulary, for an axion are given. Reaction $μ^+ μ^- \to Z^0 H^0$ is some "generalization" of the well-known "Bjorken process" for the case of $ e^+ e^-$ collisions. Various distributions for both the processes above are illustrated for the energies, which will be reached at future $μ^+ μ^-$ colliders. Study of those processes will be evidently complementary to the precision measurements at the Higgs resonance region.

Analysis of the anomalous events $e^{+}\,e^{-}\,\rightarrow\, l^{+}\, ł^{-}\,γ\,γ$

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.

Anomalous di-photon production at LEP: possible consequences at FNAL hadron collider

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.

LEP $e^{+}\,e^{-}\,\rightarrow\,μ^{+}\, μ^{-}\,γ\,γ$ events and their consequences at future $e^+e^-$ colliders

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.
