1  HAYRAPETYAN 2023F search for anomalous top $\rightarrow$ leptons decay via effective operators. No signal observed. Limits placed on EFT operators.
2  BALDIN 1976 is a 70 GeV Serpukhov experiment. Value is per ${}^{}\mathrm {Al}$ nucleus at $\theta $ = 0. For other charges in range $-0.5$ to $-3.0$, CL = 90$\%$ limit is ($2.6 \times 10^{-36})/\vert $(charge)$\vert $ for mass range (2.1$-$9.4 GeV)${\times }\vert $(charge)$\vert $. Assumes stable particle interacting with matter as do antiprotons.
3  ALBROW 1975 is a CERN ISR experiment with $\mathit E_{{\mathrm {cm}}}$ = 53 GeV. $\theta $ = 40 mr. See figure 5 for mass ranges up to 35 GeV.
4  JOVANOVICH 1975 is a CERN ISR 26$+26$ and 15$+15$ GeV ${{\mathit p}}{{\mathit p}}$ experiment. Figure 4 covers ranges $\mathit Q$ = 1/3 to 2 and $\mathit m$ = 3 to 26 GeV. Value is per GeV momentum.
5  APPEL 1974 is NAL 300 GeV ${{\mathit p}}{}^{}\mathrm {W}$ experiment. Studies forward production of heavy (up to 24 GeV) charged particles with momenta 24$-$200 GeV ($–$charge) and 40$-$150 GeV ($+$charge). Above typical value is for 75 GeV and is per GeV momentum per nucleon.
6  ALPER 1973 is CERN ISR 26$+26$ GeV ${{\mathit p}}{{\mathit p}}$ experiment. $\mathit p$ $>$0.9 GeV, 0.2 $<$ $\beta $ $<$0.65.
7  ANTIPOV 1971B is from same 70 GeV ${{\mathit p}}$ experiment as ANTIPOV 1971C and BINON 1969.
8  ANTIPOV 1971C limit inferred from flux ratio. 70 GeV ${{\mathit p}}$ experiment.
9  DORFAN 1965 is a 30 ${\mathrm {GeV/}}\mathit c$ ${{\mathit p}}$ experiment at BNL. Units are per GeV momentum per nucleus.
