Аннотация:Photoproduction of beauty quarks in events with two jets and an electron associated with one of the jets
has been studied with the ZEUS detector at HERA using an integrated luminosity of 120 pbÀ1 . The
fractions of events containing b quarks, and also of events containing c quarks, were extracted from a
likelihood fit using variables sensitive to electron identification as well as to semileptonic decays. Total
and differential cross sections for beauty and charm production were measured and compared with next-
to-leading-order QCD calculations and Monte Carlo models.
