Abstract
We report on the extraction of the structure functions F-2 and Delta xF(3) = xF(3)(nu) - xF(3)(<()over bar>) from CCFR nu (mu)-Fe and <()over bar>(mu)-Fe differential cross sections. The extraction is performed in a physics model independent (PMI) way. This first measurement of Delta xF(3), which is useful in testing models of heavy charm production, is higher than current theoretical predictions. The ratio of the F2 (PMI) values measured in nu (mu) and mu scattering is in agreement (within 5%) with the NLO predictions using massive charm production schemes, thus resolving the long-standing discrepancy between the two sets of data. In addition, measurements of F-L (or, equivalently, R) and 2xF(1) are reported in the kinematic region where anomalous nuclear effects in R are observed at HERMES.
