Charm Production and QCD Analysis at HERA and LHC

Understand

This review is devoted to the study of charm production in ep and pp collisions.

• The total set of measurements obtained by the two collaborations H1 and ZEUS from HERA and their combination is outlined, as well as complementary data obtained by the LHCb collaboration at the LHC.
• After fitting the parton distribution functions the charm production cross sections are predicted within perturbative QCD at next-to-leading order using the fixed-flavour-number scheme.
• Agreement with the data is found.
