Low Q^2 low x structure function analysis of CCFR data for F2

TL;DR

This paper presents a new analysis of structure functions from CCFR neutrino data at very low x and Q^2, comparing results with muon scattering data to investigate discrepancies and differences in F2 behavior.

Contribution

It introduces a novel analysis of CCFR data at low x and Q^2, and compares neutrino and muon scattering results to explore their differences in F2.

Findings

F2 from neutrino and muon scattering show discrepancies at low x and Q^2.

Differences in F2 behavior suggest different underlying physics in neutrino versus muon scattering.

Comparison indicates potential Q^2 dependence in the F2 differences.

Abstract

Analyses of structure functions (SFs) from neutrino and muon deep inelastic scattering data have shown discrepancies in F2 for x < 0.1. A new SF analysis of the CCFR collaboration data examining regions in x down to x=.0015 and 0.4 < Q^2 < 1.0 is presented. Comparison to corrected charged lepton scattering results for F2 from the NMC and E665 experiments are made. Differences between muon and neutrino scattering allow that the behavior of F2 from muon scattering could be different from F2 from neutrino scattering as Q^2 approaches zero. Comparisons between F2 muon and F2 neutrino are made in this limit.
