MEASUREMENT OF sin θW FROM NEUTRINO-NUCLEON SCATTERING AT NuTeV
نویسندگان
چکیده
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) = 0.2253 ± 0.0019(stat) ± 0.0010(syst), which implies MW= 80.26 ± 0.11 GeV.

On the NuTeV anomaly and the asymmetry of the strange sea in the nucleon
Our recent theoretical analysis based on the flavor SU(3) chiral quark soliton model predicts fairly large particle-antiparticle asymmetry of the strange sea in the nucleon. We point out that the predicted magnitude of asymmetry is large enough to solely resolve the so-called NuTeV anomaly on the fundamental parameter sin θW in the standard model. At the early stage of high-energy deep-inelasti...

متن کاملElectroweak Physics at NuTeV
The NuTeV experiment at Fermilab presents a determination of the electroweak mixing angle. High purity, large statistics samples of νμN and νμN events allow the use of the Paschos-Wolfenstein relation, a technique which considerably reduces systematic errors associated with charm production and other sources. Within the Standard Model, this measurement of sin θW indirectly determines the W boso...
متن کاملThe Parton Structure of the Nucleon and Precision Determination of the Weinberg Angle in Neutrino Scattering
A recently completed next-to-leading-order program to calculate neutrino cross sections, including power-suppressed mass correction terms, has been applied to evaluate the Paschos-Wolfenstein relation, in order to assess quantitatively the validity and significance of the NuTeV anomaly. In particular, we carefully study the shift of sin θW obtained in calculations by using a new generation of P...
متن کامل→ ν s oscillations with large neutrino mass in NuTeV ?
We propose an explanation of the NuTeV anomaly in terms of oscillations of electron neutrinos into sterile neutrinos. We derive an average transition probability Pνe→νs ≃ 0.21±0.07, which is compatible with other neutrino data if the mass-squared difference that drives the oscillations is ∆m ∼ 10− 100 eV. The NuTeV collaboration measured recently [1] a value of the electroweak parameter sin θW ...
