${{\overline{\mathit p}}}$ MEAN LIFE INSPIRE search

Of the two astrophysical limits here, that of GEER 2000D involves considerably more refinements in its modeling. The other limits come from direct observations of stored antiprotons. See also “${{\overline{\mathit p}}}$ Partial Mean Lives” after “${{\mathit p}}$ Partial Mean Lives,” below, for exclusive-mode limits. The best (lifetime/branching fraction) limit there is $7 \times 10^{5}$ years, for ${{\overline{\mathit p}}}$ $\rightarrow$ ${{\mathit e}^{-}}{{\mathit \gamma}}$. We advance only the exclusive-mode limits to our Summary Tables.
