A Measurement of xF_3(nu)-xF_3(anti-nu) and R with the CCFR Detector
Abstract
Description
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 Delta xF_3 = xF_3(nu)-xF_3(anti-nu) and R to be extracted. Delta xF_3 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 Delta xF_3 are compared to various massive charm NLO QCD models. The Q^2 dependence of R for x<0.1 has been measured for the first time.
