We study the sensitivity of certain observables to the anomalous righttensorial coupling in single top production at the LHC at $\sqrt{s}=13 \text{TeV}$. The observables consist of asymmetries constructed from the energy andangles of the decay products of the top quark produced in single top productionthrough $t$-channel. The computation is done at Leading Order (LO) andNext-to-Leading Order (NLO) in the strong coupling in the $5$ flavor scheme. Wehave estimated projected limits on the anomalous coupling, both at the partonlevel without cuts and at the particle level with cuts. We find that theasymmetries are robust with respect to the higher order QCD corrections and areindeed a very good probe of this anomalous coupling of the top. Hence they canbe used as experimental probes of the same.
