1  ALEKSEEV 1976 and ALEKSEEV 1976B are 61$-$70 GeV ${{\mathit p}}$ Serpukhov experiment. Cross section is per ${}^{}\mathrm {Pb}$ nucleus.
2  FRANKEL 1975 is extension of FRANKEL 1974 .
3  FRANKEL 1974 looks for particles produced in thick ${}^{}\mathrm {Al}$ targets by 300$-$400 ${\mathrm {GeV/}}\mathit c$ protons.
