| 摘 要： | The J/ψ hadronic decays provide good laboratory to search for the hybrid states with exotic quantum numbers. A full Partial Wave Analysis (PWA) is performed to the generated Monte Carlo J/ψ→ρηπ data, based on the design of BESⅢ detector, to study the sensitivity of searching for a possible exotic state at BESⅢ. |
| 关 键 词： | 1- exotic state π1(1400) covariant helicity-coupling amplitudes partial wave analysis |
