Comparison of Inclusive Charm and Beauty Cross Sections in Deep-inelastic Scattering at HERA with Theoretical Predictions

Abstract

The measurements of inclusive charm and beauty cross sections in deep-inelastic scattering $ep$ collisions at HERA are compared with the predictions of perturbative quantum chromodynamics from the CTEQ and MRST fitting groups, employing a range of theoretical schemes. The differences in the theoretical predictions are discussed and the theoretical uncertainties investigated.
