The Weak Mixing Angle at Low Energies
We determine the weak mixing angle in the MS-scheme, sin θ̂W (μ), at energy scales μ relevant for present and future low energy electroweak measurements. We relate the renormalization group evolution of sin θ̂W (μ) to the corresponding evolution of α̂(μ) and include higher-order terms in αs and α that had not been treated in previous analyses. We also up-date the analysis of non-perturbative, hadr...
متن کاملWeak mixing angle at low energies
1550-7998=20 We determine the weak mixing angle in the MS scheme, sin̂W , at energy scales relevant for present and future low-energy electroweak measurements. We relate the renormalization group evolution of sin̂W to the corresponding evolution of ̂ and include higher-order terms in s and that had not been treated in previous analyses. We also update the analysis of nonperturbative, hadronic c...
متن کاملA New Measurement of the Weak Mixing Angle
The E158 experiment at SLAC has made the first measurement of parity violation in electron-electron (Møller) scattering. We report a preliminary result using 50% of the accumulated data sample for the right-left parity-violating cross-section asymmetry (APV ) in the elastic scattering of 45 and 48 GeV polarized electron beams with unpolarized electrons in a liquid hydrogen target. We find APV =...
متن کاملPrecision measurement of the weak mixing angle in Møller scattering.
We report on a precision measurement of the parity-violating asymmetry in fixed target electron-electron (Møller) scattering: A(PV) = [-131 +/- 14(stat) +/- 10(syst)] x 10(-9), leading to the determination of the weak mixing angle sin2(thetaW(eff) = 0.2397 +/- 0.0010(stat) +/- 0.0008(syst), evaluated at Q2 = 0.026 GeV2. Combining this result with the measurements of sin2(thetaW(eff) at the Z0 p...
متن کاملThe radion contribution to the weak mixing angle
In the Randall-Sundrum (RS) compactification, the gap between two branes is stabilized by the vacuum expectation value of a scalar field called radion, φ. This radion behaves like a weak interaction singlet scalar field, coupling to matter through the trace of the energy momentum tensor. We find that it can induce a sizable correction to the weak mixing angle if the vacuum expectation value and...
