Production and decay of $\eta^\prime$(958) and $\eta$(1440) in $\bar{p} p$ annihilation at rest
/ Amsler, Claude (U. Zurich (main)) ; Anisovich, A V (U. Bonn (main)) ; Baker, C A (Rutherford) ; Barnett, B M (U. Bonn (main)) ; Batty, C J (Rutherford) ; Blum, P (Karlsruhe U.) ; Braune, K (LMU Munich (main)) ; Credé, V (U. Bonn (main)) ; Crowe, K M (LBNL, Berkeley) ; Doser, M (CERN) et al.
We report on a study of four reactions in $\bar{\mathrm p}{\mathrm p}$ annihilation at rest, of $\bar{\mathrm p}{\mathrm p} \rightarrow 2\pi^ + 2\pi^-\eta$, $\bar{\mathrm p}{\mathrm p} \rightarrow 2\pi^ + 2\pi^- 2\pi^0$, $\bar{\mathrm p}{\mathrm p} \rightarrow 2\pi^ + 2\pi^-\gamma$ and $\bar{\mathrm p}{\mathrm p}\rightarrow 4\pi^0\eta$. The $\eta^\prime$ and the $\eta$(1440) are seen in their decays into $\pi^ + \pi^-\eta$, $\pi^0\pi^0\eta$ and $\pi^ + \pi^-\gamma$ ; no signal is seen in the $4\pi$ invariant mass distribution. [...]

A partial wave analysis of pbar-p -> eta-eta-pizero data from the Crystal Barrel experiment is made in terms of s-channel resonances. The decay channels a_0(980)-eta, f_0(1770)-pi and f_0(2105)-pi provide evidence for two I = 1 J^{PC} = 0^{-+} resonances. [...]

Study of pbar-p -> eta-eta-pizero-pizero in flight
/ Anisovich, A.V. (St. Petersburg, INP) ; Baker, C.A. (Rutherford) ; Batty, C.J. (Rutherford) ; Bugg, D.V. (Queen Mary, U. of London) ; Nikonov, V.A. (St. Petersburg, INP) ; Sarantsev, A.V. (St. Petersburg, INP) ; Sarantsev, V.V. (St. Petersburg, INP) ; Zou, B.S. (Queen Mary, U. of London)
An analysis of data on pbar-p -> eta-eta-pizero-pizero is presented at pbar beam momenta 600 to 1940 MeV/c. There is evidence for an I = 1, J^PC = 2^-+ resonance in eta-eta-pizero with mass M = 1880 +- 20 MeV and width 255 +- 45 MeV, decaying strongly a2(1320)-eta; it is too strong to be explained as the high mass tail of \pi_2(1670) -> a2(1320)-eta.

New Crystal Barrel data are reported for pbar-p -> omega-eta and pbar-p -> omega-pizero-pizero with omega decaying to piplus-piminus-pizero. The omega-eta data confirm angular distributions obtained earlier from data where omega -> pizero-gamma. [...]

Combined analysis of meson channels with I=1, C = -1 from 1940 to 2410 MeV
/ Anisovich, A.V. (St. Petersburg, INP) ; Baker, C.A. (Rutherford) ; Batty, C.J. (Rutherford) ; Bugg, D.V. (Queen Mary, U. of London) ; Montanet, L. (CERN) ; Nikonov, V.A.

New Crystal Barrel data are reported for pbar-p -> omega-pizero and pbar-p -> omega eta-pizero with omega decaying to piplus-piminus-pizero. The shapes of angular distributions agree well with those for data where omega -> pizero-gamma; this is a valuable cross-check on systematic errors. [...]

We present data on pbar-p -> eta-eta-pizero at beam momenta of 600, 900, 1050, and 1200 MeV/c. At the higher three momenta, a signal is clearly visible due to pbar-p -> f_0(1770)-pizero, f_0(1770) -> eta-eta. [...]
