T-odd correlations from CP violating anomalous top-quark couplings revisited

Abstract

We revisit the effect of CP violating anomalous top-quark couplings in $t\bar{t}$ production and decay. We consider $t\bar{t}$ production through gluon fusion (and light $q\bar{q}$ annihilation) followed by top-quark decay into $bW$ or $b\ell \nu$. We find explicit analytic expressions for all the triple products generated by the anomalous couplings that fully incorporate all spin correlations. Our results serve as a starting point for numerical simulations for the LHC.
