One-loop weak corrections to three-jet observables at the Z pole

Abstract

We briefly illustrate the impact of the genuinely weak one-loop virtual terms of the $\mathcal{O}(\hat{I}{\pm }_{\mathrm{S}}\hat{I}{\pm }_{\mathrm{EW}}^3)$ factorisable corrections to the three-jet cross section at $\sqrt{s}=M_Z$. Their importance for the measurement of $\hat{I}{\pm }_{\mathrm{S}}$ at GigaZ luminosities is emphasised
