Our main aim in this paper is to constrain the effective field theory describing the top quark couplings through the eâe+âttÂ¯+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 ttÂ¯Î³, ttÂ¯Z, and ttÂ¯g for each benchmark scenario using the dileptonic ttÂ¯ final state. We show that the 95% CL limits on dimensionless Wilson coefficients cÂ¯i considered in this analysis could be probed down to 10â4.
