Title: A Next-to-Leading Order QCD Analysis of Neutrino - Iron Structure Functions at the Tevatron

Abstract

Nucleon structure functions measured in neutrino-iron and antineutrinoiron charged-current interactions are presented. The data were taken in two high-energy high-statistics runs by the LAB-E detector at the Fermilab Tevatron. Structure functions are extracted from a sample of 950,000 neutrino and 170,000 antineutrino events with neutrino energies from 30 to 360 Ge V. The structure functions $$F_2$$ and $$xF_3$$ are compared with the the predictions of perturbative Quantum Chromodynamics (PQCD). The combined non-singlet and singlet evolution in the context of PQCD gives NL0(4) . 2 value of $$\Lambda^{NLO,(4)}_{\overline MS}$$ = 337 ± 28 (exp.) MeV, which corresponds to $$\alpha_s$$ ($$M^2_z$$) = 0.119 ± 0.002 (exp.) ± 0.004 (theory), and with a gluon distribution given by $$xG(x,Q^2_0 = 5 GeV^2$$ ) = (2.22±0.34) x ($$1-x)^{4.65 \pm 0.68}$$
