Search for the fourth standard model family fermions and E-6 quarks at mu(+)mu(-) colliders

Abstract

The potential of mu(+) u(-) colliders to investigate the fourth standard model family fermions predicted by flavor democracy is analyzed. It is shown that muon colliders are advantageous for both pair production of fourth family fermions and resonance production of fourth family quarkonia. Also, isosinglet quark production at mu(+) mu(-) colliders is investigated.
