On Higgs production in γγ collisions

Abstract

I review recent progress on the Higgs production in γγ collisions at the photon mode of the Next Linear Collider (NLC). I mainly focus on two particular topics. The first topic is the Higgs-two photon vertex, which is sensitive to new physics, and can be considered a counter of the number of new heavy particles. I recall the results on QCD and electroweak two loop radiative corrections. The second topic is the heavy quark anti-quark pair production in γγ collisions, which is the dominant background process for the Higgs production at mH<150 GeV.mH<150GeV. We suggest a procedure for the resummation of double (DL) and single (SL) logarithms in the process γγ→b.γγ→bb̄. © 2001 American Institute of Physics
