/ Abstract
We report on the extraction of the structure functions F2 and from CCFR νμ-Fe and -Fe differential cross sections. The extraction is performed in a physics model independent (PMI) way. This first measuremant for ΔxF3, which is useful in testing models of heavy charm production, is higher than current theoretical predictions. Within 5% the F2 (PMI) values measured in νμ and μ scattering are in agreement with the predictions of Next-to-Leading-Order PDFs (using massive charm production schemes), thus resolving the long-standing discrepancy between the two measurements.
