Query: Radions in a $\gamma\gamma$ collider   We study the resonance production of radions via $\gamma\gamma$ fusion in the
Randall-Sundrum model. We find that the cross section of the process in the
$\gamma\gamma$ mode of a linear collider (LC) can be of similar size as in the
$e^+e^-$ collision mode, if the radion is heavy. We consider the possible
curvature-Higgs mixing in the model, and we find that the mixing should be
constrained in order to avoid an unphysical state. The process $\gamma\gamma
\to \phi$ is the main source of radions at LC near the conformal limit. We
consider both the decay modes of radion with curvature-Higgs mixing and
without. Our results show that the radion with mass below 800 GeV could be
detected at LC with any mixing parameter and vacuum expectation value of the
radion around 1 TeV.
