Description
The copious production of charm quarks at HERA has yielded a detailed
understanding of QCD dynamics, the only measure of the charm contribution
to the proton structure, as well as a measurement of the charm mass.
Although with smaller samples, measurements of beauty production also
place constraints on the structure of the proton and allow a measurement
of the beauty quark mass. Several measurements of heavy quark production
in deep inelastic scattering, using different decay modes, are presented,
both new individual measurements from the H1 and ZEUS collaborations, as well
as combined data. These provide a powerful vindication of the form of the gluon
density in the proton derived from scaling violations of inclusive
deep inelastic scattering data. QCD fits to the data lead to measurements of the
charm and beauty masses and also provide precise predictions for
e.g. W and Z production at the LHC.
