Two-photon production of heavy Higgs boson and fourth fermion generation

  • Published:
Lettere al Nuovo Cimento (1971-1985)

Summary

We study the two-photon production of heavy Higgs boson withm H ≳ 0.2 TeV/c2 in e+e--collisions at √s = 1, √2 and 2 TeV. If there exists the fourth generation of fermions which contributes to the closed fermion loop in γγ → H, the cross-section σ2γ(e+e- → e+e-H) form H∼ (200÷250) GeV/c2 can become of the same size of\(\sigma _{2w} (e^ + e^ - \to \nu \bar \nu H)\) due to the WW-fusion mechanism, depending on the fermion mass values.
