NuTeV Structure Function Measurement
نویسنده
چکیده
Abstract. The NuTeV experiment obtained high statistics samples of neutrino and antineutrino charged current events during the 1996-1997 Fermilab fixed target run. The experiment combines sign-selected neutrino and antineutrino beams and the upgraded CCFR iron-scintillator neutrino detector. A precision continuous calibration beam was used to determine the muon and hadron energy scales to a precision of 0.7% and 0.43% respectively. The structure functions F2(x,Q) and xF3(x,Q) obtained by fitting the y-dependence of the sum and the difference of the ν and ν differential cross sections are presented.

Differential Cross Section Results from Nutev
The NuTeV experiment has collected high statistics, high energy samples of ν and ν charged-current interactions using the sign-selected Fermilab neutrino beam. NuTeV has extracted ν and ν differential cross sections for DIS single-muon production at moderate x > 0.015 and average Q ∼ 15 GeV. Differential cross sections and structure function results are presented. The NuTeV measurement has impr...
متن کاملMEASUREMENT OF sin θW FROM NEUTRINO-NUCLEON SCATTERING AT NuTeV
We report the measurement of sin θW in ν − N deep inelastic scattering from the NuTeV experiment. Using separate neutrino and anti-neutrino beams, NuTeV is able to determine sin θW with low systematic errors by measuring the Paschos-Wolfenstein variable R, a ratio of differences of neutrino and anti-neutrino neutral-current and charged-current cross-sections. NuTeV measures sin θW (on−shell) = ...

متن کاملCharge Symmetry Violating Contributions to Neutrino Reactions
The NuTeV group has measured charged and neutral current reactions for neutrinos on iron targets. Ratios of these cross sections provide an independent measurement of the Weinberg angle. The NuTeV value for sin θW is three standard deviations larger than the value measured in other electroweak processes. By reviewing theoretical estimates of parton charge symmetry violation (CSV), we study CSV ...
متن کاملDeep-inelastic-scattering at Ccfr/nutev
We present recent QCD results in ν−N scattering at the Fermilab CCFR/NuTeV experiments. We present the latest Next-to-Next-Leading order strong coupling constant, αs, extracted from Gross-Llewellyn-Smith sum rule. The value of αs from this measurement, at the mass of Z boson, is α s (M 2 Z ) = 0.114 −0.012 . We also present a preliminary result of the CCFR F2 at large-x. This measurement of F2 ...
