Measurement of D∗± meson production and determination of at low Q2 in deep-inelastic scattering at HERA
Inclusive production of D ∗ mesons in deep-inelastic ep scattering at HERA is studied in the range 5< Q 2 <100 GeV 2 of the photon virtuality and 0.02< y <0.7 of the inelasticity of the scattering process. The observed phase space for the D ∗ meson is p T ( D ∗ )>1.25 GeV and | η (...

Summary: | Inclusive production of
D
∗
mesons in deep-inelastic
ep
scattering at HERA is studied in the range 5<
Q
2
<100 GeV
2
of the photon virtuality and 0.02<
y
<0.7 of the inelasticity of the scattering process. The observed phase space for the
D
∗
meson is
p
T
(
D
∗
)>1.25 GeV and |
η
(
D
∗
)|<1.8. The data sample corresponds to an integrated luminosity of 348 pb

collected with the H1 detector. Single and double differential cross sections are measured and the charm contribution
to the proton structure function

is determined. The results are compared to perturbative QCD predictions at next-to-leading order implementing different schemes for the charm mass treatment and with Monte Carlo models based on leading order matrix elements with parton showers. |
