Abstract：
The cross sections of single and double photon production are calculated in both direct and resolved processes in hard photoproduction at HERA in the leading order(LO)of QCD.The results indicate that single photon production is dominated by direct processes while x_T≤0.15.The main sources of double photons are the subprocesses of resolved processes gg→γγ and qq→γγ.Under the same condition,the double photon cross section is of the same order as those in h₁h₂→γγX.The study of double photon production may be helpful for exploring the structure of resolved photon.
