Search for monochromatic pion emission in pp annihilation from atomic p states

Academic Article


  • Narrow states observable through the emission of monoenergetic charged pions have been searched for in pp annihilation at rest in a gaseous hydrogen target where annihilation from atomic angular momentum L = 1 states dominates. No structure is observed. The 5σ upper limit for the production of narrow states in the mass range 1100-1670 MeV is 2 × 10-3 of all annihilations. © 1985.
