D* ( Plus Jets) In Deep Inelastic Scattering And Photoproduction
35TH INTERNATIONAL CONFERENCE OF HIGH ENERGY PHYSICS (ICHEP 2010)（2010）
摘要
New results on charm quark production at HERA in an increased phase space in deep-inelastic scattering and photoproduction are discussed. Single & double-differential cross section distributions are compared to next-to-leading order QCD calculations as well as to MC@NLO in the photoproduction regime. The charm contribution to the proton structure, F-2(c (c) over bar) (x,Q(2)), is determined with different experimental techniques and finally combined.
