  QED radiative corrections to the cross-section of muon-antimuon annihilation
into Higgs boson and photon are calculated within the 1-loop approximation. We
write down the expression for cross-section in the form of Drell-Yan process,
taking into account higher order leading logs. The non-singlet structure
functions of fermions are shown to obey here evolution equations of twist-3
operators. Numerical estimation shows an importance of the correction in the
region close to the threshold of Higgs production.
