Probing top quark anomalous moments in W boson associated single top quark production at the LHC using polarization and spin correlation

Abstract

We study the W boson associated single top quark production at the Large Hadron Collider (LHC) to probe anomalous chromo-magnetic and chromo-electric moments of the top quark with the help of polarization and spin correlation observables besides the cross-section in the leptonic final state. We reconstruct the two neutrinos in the final state using the MT2 assisted on-shell (MAOS) reconstruction method to measure the polarization and spin correlation asymmetries of the top quark and the W boson. We estimate the limits on the anomalous moments in a detector-level simulation considering possible backgrounds for a few sets of integrated luminosities and examined the effect of systematic uncertainties.
