Measurements of F_2 and xF_3(nu)-xF_3(nubar) from CCFR nu_mu-Fe and   nubar_mu-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(nu)-xF_3(nubar) from CCFR nu_mu-Fe and nubar_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 testingmodels of heavy charm production, is higher than current theoretical predictions. The ratio of the F_2(PMI) values measured in nu_mu and nubar_mu scattering is in agreement (within 5%) with the predictions of NLO PDFS using massive charm production schemes, thus resolvin long-standing discrepancy between the two sets of data.
