sections have been made in deep inelastic scattering at HERA for jet
transverse energy ET_jet > 6 GeV and pseudorapidity -1.0 < eta_jet <
1.5 for the kinematic region of photon virtuality Q2 > 6 GeV2 and
elasticity variable 0.07 < y < 0.625. The data were collected with the
H1 detector in the years 2006 and 2007 corresponding to an integrated
luminosity of 189 pb^-1. The number of charm and beauty jets are
determined using variables reconstructed by the H1 vertex detector
including the impact parameter of tracks to the primary vertex and the
position of the secondary vertex. The measurements are compared with
QCD predictions.
