Measurements of F2 and xF3v-xF3v from CCPR vμ-Fe and (v)over-barμ-Fe data in a physics model-independent way

We report on the extraction of the structure functions F-2 and Delta xF(3) = xF(3)(upsilon) - xF(3)(<()over bar>) from CCFR upsilon (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 F-2 (PMI) values measured in upsilon (mu) and mu scattering is in agreement (within 5%) with the predictions of next-to-leading-order parton distribution functions using massive charm production schemes, thus resolving the long-standing discrepancy between the two sets of data.
