| Abstract |
Photoproduction of heavy quarks in events with two jets has been measured with
the ZEUS detector at HERA using data recorded in the years 2006-2007 corresponding to
an integrated luminosity of 128 pb-1. The
beauty and charm content was extracted using the decay-length significance of the b and c
hadrons and the invariant mass of the decay vertices. Differential cross
sections as a function of PTJet and &etaJet were
compared with the Pythia leading order plus parton shower Monte Carlo and QCD
predictions calculated at next-to-leading order. In order to study the theoretical
description of higher-order effects correlations between the two highest energy
jets were also investigated. |
