Description
Photoproduction of beauty and charm quarks in events with at least two jets
has been measured with the ZEUS detector at HERA using an integrated
luminosity of 133 pb-1. The fractions of jets containing b and c quarks
were extracted using the invariant mass of charged tracks associated to
secondary vertices and the decay-length significance of these vertices.
Differential cross sections as a function of jet transverse momentum,
pT(Jet), and pseudorapidity, eta(Jet), were measured.
The data are compared with previous measurements and are well described by
next-to-leading order QCD predictions.
