1AAD 2024AC limit is from the measurement of the ${{\mathit t}}{{\overline{\mathit t}}}$ production cross section with large missing $\not E_T$ in ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV.
2MCFARLAND 1998 assumed a flavor universal interaction. Neutrinos were mostly of muon type.
