Strange sea and alpha (sub s) measurements from nu - N deep inelastic scattering at CCFR/NuTeV

摘要

We present the latest Next-to-Next-Leading order strong coupling constant, (alpha)(sub s), extracted from Gross-Llewellyn-Smith sum rule. The value of (alpha)(sub s) from this measurement, at the mass of Z boson, is (alpha)(sub s) (sup NNLO) (M(sup 2)(sub Z)) = 0.114(sup +0.009)(sub -0.012). We discuss the previous strange sea quark measurement from the CCFR experiment and the prospects for improvements of the measurement in the NuTeV experiment.
