Description
Measurements of open beauty and charm production cross sections in deep inelastic $ep$ scattering at HERA from the H1 and ZEUS Collaborations are combined. Reduced cross sections for beauty and charm production are obtained in the kinematic range of photon virtuality 2.5 ≤ Q$^2$ ≤ 2000 GeV$^2$ 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 data are compared to perturbative QCD predictions.
