Learning to pinpoint effective operators at the LHC: a study of the t t ¯ b b ¯ $$ \mathrm{t}\overline{\mathrm{t}}\mathrm{b}\overline{\mathrm{b}} $$ signature

Abstract In the context of the Standard Model effective field theory (SMEFT), we study the LHC sensitivity to four fermion operators involving heavy quarks by employing cross section measurements in the t t ¯ b b ¯ $$ t\overline{t}b\overline{b} $$ final state. Starting from the measurement of total...
