Virtual photon structure functions and the parton content of the electron
We point out that in processes involving the parton content of the photon the usual effective photon approximation should be modified. The reason is that the parton content of virtual photons is logarithmically suppressed compared to real photons. We describe this suppression using several simple, physically motivated Ansa$uml---tze. Although the …
