Possible evidence for narrow bound states related to the $p\overline{p}$ system

A search for mesonic structure in the pp system below threshold is reported. Bound states are observed for the first time by observing gamma -rays accompanying the annihilation of stopped p in liquid hydrogen. A novel NaI handling technique is reported. Three narrow structures are observed related t...

Sumario:A search for mesonic structure in the pp system below threshold is reported. Bound states are observed for the first time by observing gamma -rays accompanying the annihilation of stopped p in liquid hydrogen. A novel NaI handling technique is reported. Three narrow structures are observed related to the pp system at 183, 216 and 420 MeV, with confidence levels of 1%, 2.5% and 1.8% respectively. (47 refs).
