This paper presents partial wave analysis results of ethapi+pi- and omegaomega systems, confirming known resonances and providing evidence for new mesons, advancing understanding of meson spectroscopy.
Contribution
It performs both mass-independent and mass-dependent partial wave analyses, revealing detailed resonance structures in ethapi+pi- and omegaomega systems.
Findings
Resonances observed in ethapi+pi- system at JPC=1--,3--,2++,4++
Confirmation of f2(1565) and f4(2050) in omegaomega system
Evidence for a new f4(2300) meson
Abstract
Results of the ethapi+pi- and omegaomega final state partial wave analysis(PWA) are presented. The mass-independent and the mass-dependent PWA were performed. The ethapi+pi- system PWA results in the observation of the resonances in the JPC=1--,3--,2++ and 4++ waves. The results of the omegaomega system PWA confirms the existence of the f2(1565) and f4(2050). The f2(1950) is observed. There is evidence for a f4(2300) meson.
