A METHOD FOR CALCULATING PHOTON STRUCTURE FUNCTION IN DEEP INELASTIC SCATTERING

  • This paper discusses the behaviors of the photon structure function, which is considered as a superposition of a hadronic and a pointlike component. The pointlike component is calculated in the quark parton model. The hadronic part is calculated in the vector dominance model. The valence quark distribution function of ρ0 is assumed to be the same as that of π0. The π0 valence quark distribution function is represented by an analytic expression in the leading logarithm approximation from the Altarelli-Parisi equation. Results obtained are in agreement with experimental data.

A METHOD FOR CALCULATING PHOTON STRUCTURE FUNCTION IN DEEP INELASTIC SCATTERING

Abstract: This paper discusses the behaviors of the photon structure function, which is considered as a superposition of a hadronic and a pointlike component. The pointlike component is calculated in the quark parton model. The hadronic part is calculated in the vector dominance model. The valence quark distribution function of ρ0 is assumed to be the same as that of π0. The π0 valence quark distribution function is represented by an analytic expression in the leading logarithm approximation from the Altarelli-Parisi equation. Results obtained are in agreement with experimental data.
