Antiproton annihilation at rest in liquid deuterium into ππ0π0pS

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

With the Crystal Barrel detector, the final state ππ0π0pS at rest in liquid deuterium was measured for the first time. A preliminary partial-wave analysis was performed, which required two interesting features: besides the ρ(770), a second pole was needed in the ππP-wave and a narrow resonance in the ππS-wave, slightly above 1500 MeV/c2. With the same parametrization a high-statistics π+ππ0 data set could also be well described.
