Query: Radiative Corrections to $\gamma\gamma\to W^+ W^-$ in the Electroweak
  Standard Model   The cross-section for $\gamma\gamma\to W^+ W^-$ with arbitrary polarized
photons and W bosons is calculated within the electroweak Standard Model
including the complete virtual and soft-photonic ${\cal O}(\alpha)$
corrections. We present a detailed numerical discussion of the complete
radiative corrections and an analytical investigation of the leading
corrections. It turns out that in the on-shell renormalization scheme for fixed
$M_W$ no leading corrections associated with the running of $\alpha$ or heavy
top-quark and Higgs-boson masses occur. The corrections are typically of the
order of 10\%. They reach, however, larger values where the lowest-order
cross-sections are suppressed.
