Analysis of narrow effects in pp annihilations / Defoix, C (Coll France, Paris, France)
The author describes briefly some methods of analysis that final states involving a number of like particles require. A first method consists of separating two competing channels to minimize the reflections due to the undesirable one. [...]

Experimental analysis of the reaction pp to pi /sup +/ pi /sup -/ pi /sup +/ pi /sup -/ pi /sup 0/ at rest (non- omega /sup 0/ events) evidence for a rho /sup 0/ rho /sup 0/ effect around 1400 MeV / Defoix, C ; Espigat, P
Concerns a sample of 25800 pp to pi /sup +/ pi /sup -/ pi /sup +/ pi /sup -/ pi /sup 0/ annihilations at rest, produced in the 81 cm HBC at CERN. The omega /sup 0/ pi /sup +/ pi /sup -/ and eta /sup 0/ pi /sup +/ pi /sup -/ final states have been already studied by the CERN- College de France collaboration (see abstr. [...]

Analysis of p.bar.p $\to \omega \pi \pi$ in flight with the Crystal Barrel Detector / Bischoff, S (CERN) /Crystal Barrel Collaboration
This article describes the analysis of pp-annihilation in flight into the omega pi /sup 0/ pi /sup 0/- and omega pi /sup +/ pi /sup -/ final states. The partial wave analysis shows evidence for a new isovector axial vector state b/sub 1/(1800) in its decay mode omega pi . [...]

A high resolution search for the tensor glueball / Seth, K K (CERN) /Crystal Barrel Collaboration
A search for the putative candidate for the narrow tensor (2/sup ++/) glueball, xi (2230), identified by BES(BEPC) in the radiative decay of J/ psi , has been made using the Crystal Barrel detector at LEAR (CERN). No evidence for any enhancement in pp to pi /sup 0/ pi /sup 0 /, eta eta , and pi /sup 0/ eta channels is observed in the region 2222 to 2240 MeV. [...]

Present status of the omega pi pi decay of the A/sub 2/ from the pp annihilations at 700 MeV/c / Defoix, C ; Dobrzynski, L ; Espigat, P
With the aim of clearer understanding of the A/sub 2/ to omega pi pi decay mode, some partial results for the reaction pp to pi /sup +/ pi /sup +/ pi /sup +/ pi /sup -/ pi /sup -/ pi /sup -/ pi /sup 0/ at 725 MeV/c are presented and analysed. (3 refs)..

Search for structure in the mass region 2220 to 2240 $MeV/c^{2}$ in a $\overline{p} p \to \pi^{0} \pi^{0}$, $\eta \pi^{0}$, $\eta \eta$ formation experiment / Röthel, W (CERN) /Crystal Barrel Collaboration
Results of a search for narrow resonances in a pp formation experiment with the Crystal Barrel Detector at LEAR are presented. The cross sections for pp to pi /sup 0/ pi /sup 0/, eta pi /sup 0/ and eta eta are determined for annihilation at 9 momenta in the region square root (s)=2222-2240 MeV/c/sup 2/. [...]

What have we learned on mesons? / Moebes, J P (CERN)
The author discusses pp annihilation processes involving resonances. These include omega /sup 0/; KK-threshold effects; pi /sub N/(1016), S*(1070); 'diffractive' mesons: A/sub 1/, B, C; KK pi -effects: D/sub 1/E/sub 1/F/sub 1/. [...]

Search for the tensor glueball candidate $\xi$ (2230) in an antiproton-proton formation experiment / Röthel, W (CERN) /Crystal Barrel Collaboration
Results of a search for the tensor (2/sup ++/) glueball candidate xi (2230) are presented. A scan of the formation of xi (2230) in the mass region square root s=2222.7-2239.7 MeV/c/sup 2/ was made using the Crystal Barrel Detector at LEAR (CERN). [...]
