Nonrelativistic Quark Model Calculation of the S parameter
Abstract
A critical review is presented of the attempts to estimate the Strong Interactions contributions to the parameter S (L10 in the QCD Chiral Version). In particular it is discussed why the estimations done for Technicolor are unreliable. S is calculated for heavy doublets of Techniquarks using the Nonrelativistic Quark Model and keeping v 0.25 TeV fixed. It is found that heavy Techniquarks decouple, so it is possible to obtain values for S in agreement with present experimental data.
