TL;DR: In this paper, a combined analysis of 3 π 0, ππ 0 and π0 η data in the mass range 1960 to 2410 MeV is presented, which is made consistent also with ηπ 0 data, reported separately.

TL;DR: In this article, a partial wave analysis of p p→ηηπ 0 data from the Crystal Barrel experiment is made in terms of s-channel resonances, and the decay channels a0(980)η, f0(1770)π and f 0(2105)π provide evidence for two I=1, JPC=0−++ resonances.

TL;DR: An analysis of data on p p→ηηπ 0 π 0 is presented at p beam momenta 600 to 1940 MeV/c in this paper, where evidence for an I = 1, J PC = 2 −+ resonance in ηππ 0 with mass M =1880±20 MeV and width 255±45 MeV, decaying strongly to a 2 (1320) η ; it is too strong to be explained as the high mass tail of π 2 (1670)→ a 2

TL;DR: In this article, a combined partial wave analysis of these data together with data on ωπ0 is reported, which requires the presence of a JPC=3−−− state with mass M=2265±20.

TL;DR: In this paper, a high resolution search for the tensor glueball candidate ξ(2230) in a p p formation experiment π0π0 and ηη decay channels were measured in a scan of the mass region 2220meV to 2240meV.

TL;DR: In this paper, the branching ratio for the π 0 π ε 0 channel in liquid and gaseous (12 ρ STP ) hydrogen was measured to be (6.14±0.40)×10 −4.

TL;DR: In this article, partial wave analysis was performed on the Crystal Barrel data in the mass range 1960 to 2410 MeV and the ωη data defined the parameters of a 1+− I=0 resonance at 2000±20 MeV better than the earlier data.
