Oblique corrections to the W width.
The lowest-order expression for the partial W width to eν, Γ(W → eν) = GμM 3 W/(6π √ 2), has no oblique radiative corrections from new physics if the measured W mass is used. Here Gμ = (1.16639 ± 0.00002)× 10 GeV/c is the muon decay constant. For the present value ofMW = (80.14±0.27) GeV/c, and withmt = 140 GeV/c, one expects Γ(W → eν) = (224.4 ± 2.3) MeV. The total width Γtot(W ) is also expec...
متن کاملSupersymmetric Partners of Oblique Corrections
We discuss the violation of the equality of the gauge coupling and gaugino coupling in the presence of soft supersymmetry breaking. Although this is a hard supersymmetry breaking effect, there are finite contributions to this difference which can be determined as a function of the soft supersymmetry breaking masses. The largest sources of this difference are the “superoblique” corrections, whic...
متن کاملEstimation of oblique electroweak corrections.
We review the general analysis of the contributions of electroweak vacuum polarization diagrams to precision experiments. We first, review the representation of these contributions by three parameters S, T, and U, and discuss the assumptions involved in this reduction. We then discuss the contributions to these parameters from various models of new physics. We show that S can be computed by a d...
متن کاملCorrections to oblique parameters induced by anomalous vector boson couplings
We study quadratically divergent radiative corrections to the oblique parameters at CERN LEP1 induced by non-standard vector boson self-couplings. We work in the Stückelberg formalism and regulate the divergences through a gauge-invariant higher derivative scheme. Using consistency arguments together with the data we find a limit on the anomalous magnetic moment ∆κ of the W-boson, |∆κ| ∼ < 0.26.
