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. [...]

(Queen Mary, U. of London ; UCLA) ; Scott, I. (Queen Mary, U. of London ; UCLA) ; Zou, B.S. (Queen Mary, U. of London ; UCLA) et al.
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. [...]

Annihilation at rest of antiprotons and protons into neutral particles / Crystal Barrel Collaboration
Annihilation of antiprotons and protons at rest into neutral particles has been studied with the Crystal Barrel detector at LEAR. Annihilation frequencies are determined for final states containing π 0 , η , η ′ and ω mesons using a liquid and a room temperature, 12 bar, gaseous hydrogen target. [...]

Coupled channel analysis of proton-antiproton annihilation into π0π0π0, π0ηη and π0π0η / Crystal Barrel Collaboration
We confirm the existence of the two I G ( J PC ) = 0 + (0 ++ ) resonances f 0 (1370) and f 0 (1500) reported by us in earlier analyses. The analysis presented here couples the final states π 0 π 0 π 0 , π 0 π 0 η and π 0 ηη of p p annihilation at rest. [...]

Search for a new light gauge boson in π0, η and η' decays / Crystal Barrel Collaboration
Upper limits for the production of new light gauge bosons in π0, η and η′ decays have been obtained with the Crystal Barrel detector. The kinematically well-constrained reactions p̅p → π0π0 P have been studied, where P ? π 0, η, η′ decays through the emission of a single photon recoiling against a missing state X. [...]

Differential cross-section measurements of pi /sup -/p to pi /sup 0/n around the P/sub 33/ (1232) resonance / Comiso, J C ; Blasberg, D J ; Haddock, R P ; Nefkens, B M K ; Truöl, P ; Verhey, L J
Differential cross-section measurements are reported for pi /sup -/p to pi degrees n at five angles and five energies around P/sub 33/ (1232) resonance. The data are in agreement with the CERN phase shift analysis results. [...]
