QCD Corrections to $b\bar{b}/c\bar{c}$ Pair Production in Polarized $\gamma \gamma$ Collisions and the Intermediate Mass Higgs Signal

Abstract

We present production rates of the two- and three-jet final states for the processes of massive $c\bar{c}/b\bar{b}$ 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 $b\bar{b}$ quark production at $\sqrt{s_{\gamma \gamma }}\sim 100$~GeV. It is shown that the signal from intermediate mass Higgs boson is observable at photon-photon collider, although the statistical significance is substantially reduced with respect to the tree level calculation.
