Electroweak Results from Nutev
نویسنده
چکیده
We report our measurement of the weak mixing angle, sin*&, in neutrino-nucleon deep inelastic scattering in the NuTeV experiment at Fermilab. Using separate neutrino and antineutrino beams, we are able to use the Paschos-Wolfenstein relations to extract sin’ Bw with low systematic errors. Our preliminary result is sin’0~(~-~~~“) = 1 m&/m; = 0.2253 f O.O019(stat.) & O.OOlO(syst.), which in the Standard Model is equivalent to a W mass measurement of 80.26 f 0.11 GeV/c’. @ 1998 by Robert B. Drucker.

The sin θW result from NuTeV falls three standard deviations from the value determined by global electroweak fits. It has been suggested that one possible explanation for this result could be the oscillation of electron neutrinos in the NuTeV beam to sterile neutrinos. This article examines several cases of masses and mixings for 3+2 neutrino oscillation models which fit the current oscillation...
متن کاملElectroweak Physics from Nutev
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 کاملPrecision Electroweak Measurements circa 2002 *
There is not so much going on in electroweak physics nowadays, apart from the muon g − 2, it is tempting to say. Not quite so: the latest Standard Model (SM) fit performed by the LEP Electroweak Working Group [1] looks remarkably different from the one from last year. The main new result comes from the NuTeV Collaboration [2]: their measurement of the electroweak mixing angle in ν-N Deep Inelas...
متن کاملElectroweak radiative corrections to deep - inelastic neutrino scattering — implications for NuTeV ?
We calculate the O(α) electroweak corrections to chargedand neutral-current deepinelastic neutrino scattering off an isoscalar target. The full one-loop-corrected cross sections, including hard photonic corrections, are evaluated and compared to an earlier result which was used in the NuTeV analysis. In particular, we compare results that differ in input-parameter scheme, treatment of real phot...
متن کاملPrecision determination of electroweak parameters and the strange content of the proton from neutrino deep–inelastic scattering
We use recent neutrino dimuon production data combined with a global deep-inelastic parton fit to construct a new parton set, NNPDF1.2, which includes a determination of the strange and antistrange distributions of the nucleon. The result is characterized by a faithful estimation of uncertainties thanks to the use of the NNPDF methodology, and is free of model or theoretical assumptions other t...
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 ...
