Photon structure function

Figure 1. Electron-photon scattering generic Feynman diagram.

Fig 3: Photon structure function versus log Q2 for 0.3 < x < 0.5 compared to the QCD prediction explained in the text.

The quark content of the photon is described in quantum field theory by the photon structure function defined by the process $e + γ \to e +$ hadrons. It is uniquely characterized by the linear increase in the logarithm of the electronic momentum transfer log $Q$ and by the approximately linear rise in $x$ , the fraction of the quark momenta within the photon.These characteristics are borne out by the experimental analyses of the photon structure function.
