1  AAD 2021X search for LLPs which come to rest in ATLAS detector to deposit energy between collisions. No signal observed in 111 fb${}^{-1}$ of data. Limits placed in lifetime vs. mass place assuming model with gluino hadrons: e.g. m $>$ 1.4 TeV for ${{\mathit \tau}}$ $\sim{}$ $10^{-5}$ to $10^{3}$ sec.
2  ACHARYA 2021 search for dyons (carrying electric and magnetic charge) and monopoles via production and capture in 6.46 ${\mathrm {fb}}{}^{-1}$ of 13 TeV LHC data. No signal observed. Limits placed in mass vs. magnetic charge plane.
3  ALEKSEEV 1976 and ALEKSEEV 1976B are 61$-$70 GeV ${{\mathit p}}$ Serpukhov experiment. Cross section is per ${}^{}\mathrm {Pb}$ nucleus.
4  FRANKEL 1975 is extension of FRANKEL 1974.
5  FRANKEL 1974 looks for particles produced in thick ${}^{}\mathrm {Al}$ targets by 300$-$400 ${\mathrm {GeV/}}\mathit c$ protons.
