. Bounds on the absorptive (imaginary) parts of the top quark chromomagnetic ˆ µ t and chromoelectric ˆ d t dipole moments are obtained by reinterpreting the most recent LHC data in top quark pair production. It is found that both limits are of the order of 10 − 1 − 10 − 2 , which are consistent with the standard model prediction of Im (cid:2) ˆ µ t (cid:3) . The effects of the absorptive parts of the top quark dipole moments are also studied via some kinematic distributions of tt production… 

Non-diagonal contributions to $Z\gamma V^\ast$ vertex and bounds on $Z\overline{t}q$ couplings

The non-diagonal contributions to the trilinear gauge bosons couplings ZγV ∗ ( V = Z , γ ) at the one-loop level are calculated through complex flavor changing neutral currents mediated by the Z
