Abstract:

At the electron-proton collider HERA the inclusive

D~{*\pm}

meson photoproduction cross section has been measured with the H1 detector in two different, but partly overlapping, kinematical regions. For the first, where

\langle W_{\gamma p}\rangle \approx 200

\ GeV and Q~2 < 0.01\,\gev~2, the result is

\sigma(\gamma p \rightarrow c \bar{c} X) = (13.2 \pm 2.2 ~{+2.1}_{-1.7}\, ~{+9.9}_{-4.8})\,\mu b

. The second measurement for Q~2 < 4\,\gev~2 yields

\sigma(\gamma p \rightarrow c \bar{c} X) = ( 9.3 \pm 2.1 ~{+1.9}_{-1.8}\, ~{+6.9}_ {-3.2} )\,\mu b

at

\langle W_{\gamma p}\rangle \approx 142

\,GeV and

\sigma(\gamma p \rightarrow c \bar{c} X) = ( 20.6 \pm 5.5 ~ {+4.3}_{-3.9}\, ~{+15.4}_{-7.2})\,\mu b

at

\langle W_{\gamma p} \rangle \approx 230

\,GeV, respectively. The third error accounts for an additional uncertainty due to the proton and photon parton density parametrizations. Differential cross sections are presented as a function of the

D~{*\pm}

transverse momentum and rapidity. The results compare reasonably well with next-to-leading order QCD calculations. Evidence for diffractive photoproduction of charm quark is presented.
