N2 - deep-inelastic scattering cross sections from HERA are used
as input for a detailed NLO QCD analysis to study the influence
of different heavy flavour schemes on the parton distribution
functions. The optimal values of the charm mass
as a parameter in these different schemes are obtained. The
implications on the NLO predictions for W
± and Z production
cross sections at the LHC are investigated. Using the
fixed flavour number scheme, the running mass of the charm
quark is determined.Measurements of open charm production cross
sections in deep-inelastic ep scattering at HERA from the
H1 and ZEUS Collaborations are combined. Reduced cross
sections σc ¯ c
red for charm production are obtained in the kinematic
range of photon virtuality 2.5 ≤ Q2 ≤ 2000 GeV2
and Bjorken scaling variable 3 · 10−5 ≤ x ≤ 5 · 10−2. The
combination method accounts for the correlations of the
systematic uncertainties among the different data sets. The
combined charm data together with the combined inclusive
