摘要

Abstract

The sensitivity of the three top quark production process to the potential contribution of the SMEFT top-related operators was investigated. Theoretical restrictions on the Wilson coefficients of the corresponding operators are obtained for the scenarios of the LHC, HL-LHC, HE-LHC, and FCC experiments. It is shown how these restrictions change with increasing energies and luminosities of the considered scenarios. It was demonstrated that the process constrains the following four-fermion operators relatively well: \(O_{{QQ}}^{1}\) , \(O_{{Qq}}^{{1,8}}\) , \(O_{{Qq}}^{{1,1}}\) , \(O_{{Qq}}^{{3,8}}\) , \(O_{{Qq}}^{{1,3}}\) , \(O_{{Qt}}^{1}\) , \(O_{{tq}}^{8}\) , and it is also sensitive to the following operators with bosonic fields: \({{O}_{{tW}}}\) and \({{O}_{{tG}}}\) .
