Estimation 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 {ital S}, {ital T}, and {ital U} and discuss the assumptions involved in this reduction. We then dis...

| description | 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 {ital S}, {ital T}, and {ital 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 {ital S} can be computed by a dispersion relation, and we use this technique to estimate {ital S} in technicolor models of the Higgs sector. We discuss the reliability and the gauge invariance of this estimate. Finally, we present the limits on {ital S} and {ital T} imposed by current experimental results. |
