Recent QCD results in nu-N Deep Inelastic Scattering at CCFR/NuTeV

TL;DR

This paper reports recent QCD measurements from nu-N deep inelastic scattering at CCFR/NuTeV, including the determination of the strong coupling constant at NNLO, F2 structure function at large-x, and strange sea quark insights.

Contribution

It provides the first NNLO alpha-s value from nu-N scattering and compares F2 measurements with models, advancing understanding of nuclear effects and strange quark distributions.

Findings

Alpha-s(M_Z^2)=0.114^{+0.009}_{-0.012} at NNLO.

Preliminary F2 results at large-x compared with models.

Discussion on strange sea quark measurement improvements.

Abstract

We present recent QCD results in nu-N scattering at the Fermilab CCFR/NuTeV experiments. We present the latest Next-to-Next-Leading order strong coupling constant, alpha-s, extracted from Gross-Llewellyn-Smith sum rule. The value of alpha-s from this measurement, at the mass of Z boson, is alpha-s^{NNLO}(M_Z**2)=0.114^{+0.009}_{-0.012}. We also present a preliminary result of the CCFR F_2 at large-x. This measurement of F_2 is compared to other experiments and various models that provide nuclear effects. We discuss the previous strange sea quark measurement from the CCFR experiment and the prospects for improvements of the measurement in the NuTeV experiment.
