Evidence for a Charge Asymmetry on the ω Dalitz Plot
The reaction π+p→π+pω has been studied at 3.7 GeVc using data from the LRL 72-in. hydrogen bubble chamber. An analysis of the ω→π+π-π0 Dalitz plot for ∼ 4000 ω events yields no evidence for π+π-π0 states with isospin I≠0 at the level of 10-3 in intensity relative to the I=0 intensity. A similar anal...

| 520 | |a The reaction π+p→π+pω has been studied at 3.7 GeVc using data from the LRL 72-in. hydrogen bubble chamber. An analysis of the ω→π+π-π0 Dalitz plot for ∼ 4000 ω events yields no evidence for π+π-π0 states with isospin I≠0 at the level of 10-3 in intensity relative to the I=0 intensity. A similar analysis of ∼ 500 ω events produced in a kinematical region of known ρ - ω coherence yields no evidence for ρ0→π+π-π0 decays with I≠0 at the 1% level in intensity relative to the ρ0→π+π- mode. A significantly nonzero value of the charge asymmetry α=(N+-N-)(N++N-) is observed (0.179 ± 0.051) for ω events produced opposite a Δ++ (1236) in the narrow t′=|t-tmin| range [0.08 - 0.20 (GeVc)2]. We discuss four possible origins for the observed interfering amplitude, whose quantum assignments may be deduced as IG=1-, JPC=1-+: (1) C violation in ω decay (which may be ruled out), (2) C violation in ρ0→π+π-π0 decay, (3) a miscellaneous coherent background amplitude with these quantum numbers, and (4) a possible exotic resonant state with these quantum numbers. | ||

Evidence for a Charge Asymmetry on the ω Dalitz Plot |
| abstract |
The reaction π+p→π+pω has been studied at 3.7 GeVc using data from the LRL 72-in. hydrogen bubble chamber. An analysis of the ω→π+π-π0 Dalitz plot for ∼ 4000 ω events yields no evidence for π+π-π0 states with isospin I≠0 at the level of 10-3 in intensity relative to the I=0 intensity. A similar analysis of ∼ 500 ω events produced in a kinematical region of known ρ - ω coherence yields no evidence for ρ0→π+π-π0 decays with I≠0 at the 1% level in intensity relative to the ρ0→π+π- mode. A significantly nonzero value of the charge asymmetry α=(N+-N-)(N++N-) is observed (0.179 ± 0.051) for ω events produced opposite a Δ++ (1236) in the narrow t′=|t-tmin| range [0.08 - 0.20 (GeVc)2]. We discuss four possible origins for the observed interfering amplitude, whose quantum assignments may be deduced as IG=1-, JPC=1-+: (1) C violation in ω decay (which may be ruled out), (2) C violation in ρ0→π+π-π0 decay, (3) a miscellaneous coherent background amplitude with these quantum numbers, and (4) a possible exotic resonant state with these quantum numbers. |
