Has the QCD renormalization-group-improved parton content of virtual photons been observed? art. no. 074008

It is demonstrated that present e(+)e(-) and DIS ep data on the structure o f the virtual photon can be understood entirely in terms of the standard "n aive" quark-parton model box approach. Thus the QCD renormalization group ( RG) improved parton distributions of virtual photons, in particular their g luonic component, have not yet been observed. The appropriate kinematical r egions for their future observation are pointed out as well as suitable mea surements which may demonstrate their relevance.
