¹ AAIJ 2016AR search for long lived particles from ${{\mathit H}}$ $\rightarrow$ ${{\mathit X}}{{\mathit X}}$ with displaced ${{\mathit X}}$ decay vertex using 0.62 fb${}^{-1}$ at 7 TeV; limits set in Fig. 7.

² KHACHATRYAN 2016BW search for heavy stable charged particles via ToF with 2.5 fb${}^{-1}$ at 13 TeV; require stable m(gluinoball) $>$ 1610 GeV.

³ BADIER 1986 looked for long-lived particles at 300 GeV ${{\mathit \pi}^{-}}$ beam dump. The limit applies for nonstrongly interacting neutral or charged particles with mass $>$2 GeV. The limit applies for particle modes, ${{\mathit \mu}^{+}}{{\mathit \pi}^{-}}$ , ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}$ , ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ X, ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{\pm}}$ etc. See their figure 5 for the contours of limits in the mass-$\tau $ plane for each mode.
