We report on the extraction of the structure functions F2 and DeltaxF(3) = xF(nu)(3)-xF(nu;)(3) from CCFR nu(mu)-Fe and nu;(mu)-Fe differential cross sections. The extraction is performed in a physics model-independent (PMI) way. This first measurement of DeltaxF(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 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.

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.

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.

Abstract We report on a measurement of the neutrino-nucleon and antineutrino-nucleon differential cross sections in the CCFR detector. The measurement of the differential cross sections over a wide range of energies allows ΔχF 3 = χF 3 ν −χF 3 v and R to be extracted. ΔχF3 is related to the difference between the contributions of the strange and charm seas in the nucleon to production of massive charm quark. The results for ΔχF3 are compared to various massive charm NLO QCD models. The Q2 dependence of R for χWe report on a measurement of the neutrino-nucleon and antineutrino-nucleon differential cross sections in the CCFR detector.
