Anomalous top-gluon couplings in γp collision at the CERN-LHC

Abstract

We have investigated anomalous chromomagnetic and chromoelectric dipole moments of the top quark via top pair production in a γp collision at the LHC. We obtain 95% CL bounds on the anomalous couplings with various values of the integrated luminosity. Improved constraints on the anomalous couplings have been obtained compared to current limits.
