F 2 at Low Q
We analyse the data for the proton structure function F2 over the entire Q 2 domain, including especially low Q 2 , in terms of perturbative and non-perturbative QCD contributions. The small distance configurations are given by perturbative QCD, while the large distance contributions are given by the vector dominance model and, for the higher mass qq states, by the additive quark approach.

متن کامل- 9833 August 1996 An Observation on F 2 at Low x
A simple parametrisation of H1 and ZEUS data at HERA is given for the ranges in x and Q2 of 10−4 − 5.10−2 and 5 − 250 GeV2, respectively. This empirical expression is based on a strikingly similar dependence of the average charged particle multiplicity 〈n〉 on the centre of mass system energy √ s in e+e− collisions on the one hand, and the x dependence of the proton structure function F2 as meas...
متن کاملMeasurement of the Photon Structure Function F γ 2 at Low x The OPAL
Deep inelastic electron-photon scattering is studied using ee data collected by the OPAL detector at centre-of-mass energies √ see ≈ MZ0. The photon structure function F γ 2 (x,Q ) is explored in aQ range of 1.1 to 6.6 GeV at lower x values than ever before. To probe this kinematic region events are selected with a beam electron scattered into one of the OPAL luminosity calorimeters at scatteri...
