Phys. Rev. Lett. 86, 2742–2745 (2001)Measurements of F2 and xF3ν - xF3ν̅ from CCFR νμ-Fe and ν̅ μ-Fe Data in a Physics Model-Independent WayReceived 15 September 2000; published in the issue dated 26 March 2001 We report on the extraction of the structure functions F2 and ΔxF3 = xF3ν-xF3ν̅ from CCFR νμ-Fe and ν̅ μ-Fe differential cross sections. The extraction is performed in a physics model-independent (PMI) way. This first measurement of ΔxF3, 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 νμ and μ 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. © 2001 The American Physical Society URL:
