QCD corrections to bbcc pair production in polarized γγ collisions and the intermediate mass Higgs signal

We present production rates of the two- and three-jet final states for the processes of massive ccbb quark production in circularly polarized photon-photon collisions, including QCD radiative corrections. Lowest-order cross section, one-loop virtual correction, and gluon emission correction are shown to be of the same order of magnitude for bb quark production at Sγγ∼GeV. It is shown that the signal from an intermediate mass Higgs boson is observable at a photon-photon collider, though the statistical significance is substantially reduced with respect to the tree-level calculation.
