Differential Cross Section Results from Nutev
نویسنده
چکیده
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 improved systematic precision and includes data over an expanded kinematic range up to high inelasticity.

T. Bolton (for the NuTeV Collaboration) Kansas State University, Manhattan, KS 66502 USA NuTeV has performed precise measurements of neutral-current to charged-current cross section ratios using intense high energy neutrino and anti-neutrino beams on a primarily steel target at the Fermilab Tevatron. A null hypothesis test of the standard model allows the extraction sin θ W (≡ 1 − M 2 W /M 2 Z)...
متن کاملPrecise measurement of neutrino and antineutrino differential cross sections
The NuTeV experiment at Fermilab has obtained a unique high-statistics sample of neutrino and antineutrino interactions using its high-energy sign-selected beam. We present a measurement of the differential cross section for charged-current neutrino and antineutrino scattering from iron. We determine the relative to cross section, r = , at high energy with errors a factor of 2 smaller than the ...
متن کاملNuclear modification of valence-quark distributions and its effects on NuTeV sin θW anomaly
We investigated a nuclear modification difference between upand down-valence quark distributions by analyzing structure function F2 and Drell-Yan cross-section ratios. Although nuclear modifications of the valence-quark distributions themselves are rather well determined, it is difficult to find their difference from the present data. We estimated such an effect on the NuTeV sin θW value and it...
متن کاملNuTeV Structure Function Measurement
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 pre...
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) = ...
