/ Abstract
We report on the extraction of the structure functions F2 and ΔxF3=xF3ν−xF3ν from CCFR νμ-Fe and νμ-Fe differential cross sections. The extraction is performed in a physics model independent (PMI) way. This first measurement for ΔxF3, which is useful in testing models of heavy charm production, is higher than current theoretical predictions. The F2 (PMI) values measured in νμ and μ scattering are in good agreement with the predictions of Next to Leading Order PDFs (using massive charm production schemes), thus resolving the long-standing discrepancy between the two sets of data.
