Moments of the Proton F2 Structure Function at Low Q2
Abstract
The Q2 dependence of inclusive electron-proton scattering F2 structure function data in both the nucleon resonance region and the deep inelastic region, at momentum transfers below 5 (GeV/c)2, is investigated. Moments of F2 are constructed, down to momentum transfers of Q2 ~ 0.1 (GeV/c)2. The second moment is only slowly varying with Q2 down to Q2 ~ 1 (GeV/c)2, which is a reflection of duality. Below Q2 of 1 (GeV/c)2, the Q2 dependence of the moments is predominantly governed by the elastic contribution, whereas the inelastic channels still seem governed by local duality.
