Abstract

In light of the recent discovery of the importance of the isovector EMC effect for the interpretation of the NuTeV determination of sin²θ_W, it seems timely to reassess the central value and the errors on this fundamental Standard Model parameter derived from the NuTeV data. We also include earlier work on charge symmetry violation and the recent limits on a possible asymmetry between s and s¯ quarks. In addition, with these corrections we find a revised NuTeV result of sin²θ_W = 0.2232 ± 0.0013(stat) ± 0.0024(syst), which is in excellent agreement with the running of sin²θ_W predicted by the Standard Model.

A Departure from prediction: Electroweak physics at NuTeV

Conference McFarland, K S

The NuTeV experiment has performed precision measurements of the ratio of neutral-current to charged-current cross-sections in high rate, high energy neutrino and antineutrino beams on a dense, primarily steel, target. The separate neutrino and anti-neutrino beams, high statistics, and improved control of other experimental systematics, allow the determination of electroweak parameters with significantly greater precision than past {nu}N scattering experiments. Our null hypothesis test of the standard model prediction measures sin{sup 2} {theta}{sub W}{sup (on shell)} = 0.2277 {+-} 0.0013(stat) {+-} 0.0009(syst), a value which is 3.0{sigma} above the prediction. We discuss possible explanations for and implications of this discrepancy.

Measurement of the Weak Mixing Angle in Moller Scattering

Technical Report Klejda, B

The weak mixing parameter, sin{sup 2} {theta}{sub w}, is one of the fundamental parameters of the Standard Model. Its tree-level value has been measured with high precision at energies near the Z{sup 0} pole; however, due to radiative corrections at the one-loop level, the value of sin{sup 2} {theta}{sub w} is expected to change with the interaction energy. As a result, a measurement of sin{sup 2} {theta}{sub w} at low energy (Q{sup 2} << m{sub Z}, where Q{sup 2} is the momentum transfer and m{sub Z} is the Z boson mass), provides a test of the Standard Model at themore »« less

A NEW MEASUREMENT OF THE WEAK MIXING ANGLE

Technical Report Woods, M

The E158 experiment at SLAC has made the first measurement of parity violation in electron-electron (Moeller) scattering. The authors report a preliminary result using 50% of the accumulated data sample for the right-left parity-violating cross-section asymmetry (A{sub PV}) in the elastic scattering of 45 and 48 GeV polarized electron beams with unpolarized electrons in a liquid hydrogen target. They find A{sub PV} = (-160 {+-} 21(stat.) {+-} 17(syst.)) {center_dot} 10{sup -9}, with a significance of 6.3{sigma} for observing parity violation. In the context of the Standard Model, this yields a measurement of the weak mixing angle, sin{sup 2} {theta}{sub W}{supmore »« less

Electroweak measurements and neutrino oscillations: The NuTeV and BooNE experiments

Journal Article Shaevitz, Michael H - AIP Conference Proceedings

A preliminary measurement of sin{sup 2} {theta}{sub W} in {nu}-N deep inelastic scattering from the NuTeV experiment is presented. Using separate neutrino and antineutrino beams, NuTeV is able to determine sin{sup 2} {theta}{sub W} with low systematic errors. NuTeV measures sin{sup 2} {theta}{sub W}{sup (on-shell)}=0.2253{+-}0.0019(stat){+-}0.0010(syst), which implies M{sub W}=80.26{+-}0.11 GeV. Expectations are also presented for the NuTeV search for {nu}{sub {mu}}{yields}{nu}{sub {tau}} and {nu}{sub {mu}}{yields}{nu}{sub e} oscillations using the measured neutral to charged-current ratio. The future BooNE experiment is described which searches for {nu}{sub {mu}}{yields}{nu}{sub e} appearance and {nu}{sub {mu}} disappearance oscillations using a new neutrino beam created from themore »« less
