Аннотация:Numerical simulations of processes of three and four top quark hadroproduction are carried out in the SMEFT model framework. The simulated data are used to derive theoretical constraints on Wilson coefficients of relevant SMEFT operators of dimension six. Obtained limits for both cases are discussed and compared in terms of processes sensitivity to possible BSM contribution. Results show that operators Q^1_QQ and Q^1_Qt are better constrained by the process of triple top production, whereas for operator Q^1_tt more accurate limits are obtained from the production of four top quarks. The last considered operator Q^8_Qt is relatively loosely constrained by both processes.
