Extracting Top Quark CP Violating Dipole Couplings via $t\bar t\gamma$ and $t\bar tZ$ Productions at the LHC

Abstract

We propose to extract the electric and weak dipole moments of the top quark via $t\bar t\gamma$ and $t\bar t Z$ productions at the CERN LHC. With the large numbers of events available at the LHC, these dipole moments can be measured to the accuracy of $10^{-18}e cm$.
