Charm and bottom photoproduction at HERA with MC@NLO

We apply the MC@NLO formalism to the production of heavy-quark pairs in pointlike photon- hadroncollisions. By combining this result with its analogue relevant to hadron-hadroncollisions, we obtain NLO predictions matched to parton showersfor the photoproduction of Q (Q) over bar pairs. We compare MC@NLO results to the measurements of c- and b-flavoured hadronobservables performed by the H1 and ZEUS Collaborations at HERA. (C) 2011 Elsevier B.V. All rights reserved.
