Constraints on effective field theories via quadruple-differential angular decay rates from t-channel single-top-quark production at s=13 TeV with the ATLAS detector

Events with t-channel single top quarks are used to probe effective field theory operators in s=13$$ \sqrt{s}=13 $$ TeV proton–proton collision data corresponding to 140 fb−1 recorded by the ATLAS detector at the Large Hadron Collider. To extract a maximum amount of information from these events, th
