Abstract
Our main aim in this paper is to constrain the effective field theory describing the top quark couplings through the jet process. The analysis is carried out considering two different center-of-mass energies of 500 and 3000 GeV including a realistic simulation of the detector response and the main sources of background processes. The expected limits at 95\% CL are derived on the new physics couplings such as , , and for each benchmark scenario using the dileptonic final state. We show that the 95\% CL limits on dimensionless Wilson coefficients considered in this analysis could be probed down to .
