Description

In this talk, we present the results for constraining the effective field theory describing the top quark couplings through the $e^{-} e^{+} \rightarrow t \bar{t}+$jet process.
The analysis is performed at two center-of-mass energies of
500 and 3000 GeV considering a realistic simulation of the detector response and the main sources of background.
The expected upper limits at 95\% CL are obtained on the new physics couplings
using the dileptonic $t \bar{t}$ final state.
We find that the 95\% CL bounds on dimensionless Wilson coefficients considered in this analysis could be probed down to $10^{-4}$.
