Search for long-lived charge +2 hadrons

Le résumé fourni par la source

We have searched for the production of long-lived $R\ensuremath{-}{\ensuremath{\Delta}}^{++}$ hadrons, which contain a gluino in addition to three up quarks, in $\mathrm{pp}$, ${\ensuremath{\pi}}^{+}p$, and ${K}^{+}p$ interactions at 147 GeV/c. For $R\ensuremath{-}{\ensuremath{\Delta}}^{++}$'s of lifetime greater than ${10}^{\ensuremath{-}9}$ sec, and laboratory momentum greater than 2 GeV/c, we place 90%-confidence-level upper limits of 6.1 \ensuremath{\mu} b in $\mathrm{pp}$ collisions, 4.4 \ensuremath{\mu} b in ${\ensuremath{\pi}}^{+}p$, and 29 \ensuremath{\mu} b in ${K}^{+}p$.
