Abstract: We calculate one-loop (purely) weak (W) corrections of $\mathcal{O}({\ensuremath{\alpha}}_{\mathrm{S}}^{2}{\ensuremath{\alpha}}_{\mathrm{W}})$ to the partonic cross section of two jets at Tevatron and prove that they can be larger than the tree-level $\mathcal{O}({\ensuremath{\alpha}}_{\mathrm{S}}{\ensuremath{\alpha}}_{\mathrm{EW}})$ and $\mathcal{O}({\ensuremath{\alpha}}_{\mathrm{EW}}^{2})$ electroweak (EW) ones. At high transverse energy of the jets, all such corrections may lead to detectable effects of, e.g., $\ensuremath{-}10%$ or so, with respect to the leading-order (LO) QCD term of $\mathcal{O}({\ensuremath{\alpha}}_{\mathrm{S}}^{2})$, for the highest value so far probed by Run 2, depending on the factorization/renormalization scale. Besides, they increase significantly with jet transverse energy. Hence, our results show that EW corrections may be needed to fit the standard model (SM) to present and future Tevatron jet data.
