A spin-parity analysis of the 3 pi system produced in the reaction pi /sup +/d to pi /sup -/ pi /sup +/ pi /sup +/d at 4 GeV/c / Emms, M J ; Bell, I G ; Charlesworth, J A ; Crennell, D J ; Dale, M ; Jones, G T ; Kinson, J B ; Major, J V ; Sekulin, R L ; Stacey, B J et al.
A spin-parity analysis of the low-mass /sup 3/ pi system produced in the reaction pi /sup +/d to pi /sup -/ pi /sup +/ pi /sup +/d has been performed using data from an exposure of the CERN 2m bubble chamber to a pi /sup +/ beam of 4 GeV/c momentum. Unnatural parity states predominate, 1/sup +/ being much more significant than 0/sup -/ and 2 /sup -/. [...]

A partial-wave analysis of the neutral 3 pi system produced in the reaction pi /sup -/p to ( pi /sup +/ pi /sup -/ pi /sup 0/)n at 12 and 15 GeV/c / Corden, M J ; Alexander, G ; Bellamy, E H ; Corbett, I F ; Dagan, S ; Dowell, John D ; Esterling, R J ; Garvey, J ; Gnat, Y ; Green, M G et al.
Data on the charge-exchange reaction pi /sup -/p to ( pi /sup +/ pi /sup -/ pi /sup 0/)n have been taken at beam momenta of 12 and 15 GeV /c, using the CERN Omega Multiparticle Spectrometer. A partial-wave analysis has been made of the (3 pi )/sup 0/ system. [...]

$\rho$ meson production in two photon collision at LEP with L3 detector / Fedin, O (St Petersburg Nucl Phys Inst)
The reaction gamma gamma to pi /sup +/ pi /sup -/ pi /sup +/ pi /sup -/ has been studied with the L3 detector at LEP. The data sample was collected by L3 at centre-of-mass energies from 160 GeV to 202 GeV with a total integrated luminosity of 466.2 pb/sup -1/. [...]

The reaction K/sup +/d to K/sup +/ pi /sup +/ pi /sup -/d at 4.6 GeV /c / Dunwoodie, W M ; Cornet, P ; De Jongh, G ; Dehm, G ; Dufour, P ; Göbel, G ; Goldschmidt-Clermont, Yves ; Grant, A ; Grard, F ; Henri, V P et al.
The cross section is 250+or-30 mu b. A strong K* (892) signal is seen and also a broad enhancement in the Q region (M(K pi pi )<1.5 GeV) with no evidence for narrow resonances in this mass interval. [...]

$A^{-}2$ production in $\pi^{-}p$ interactions at 3.9 GeV/c / Losty, Michael J ; Alitti, J ; Chaloupka, V ; Gandois, B ; Louie, J ; Montanet, Lucien ; Paul, E ; Yaffe, D ; Zieminski, A
The reaction pi /sup -/p to A/sub 2//sup -/p at 3.9 GeV/c incident momentum is studied using data corresponding to the rho /sup 0/ pi /sup -/, eta pi /sup -/ and K/sub S//sup 0/K/sup -/ decay modes of the A/sub 2//sup -/. Unnatural parity exchange is found to be important at this energy. [...]

The decay channel A/sup -//sub 2/ to eta pi /sup -/ in the reaction pi /sup -/p to p pi /sup -/ pi /sup +/ pi /sup -/ pi /sup 0/ at 40 GeV/c / Antipov, Yu M ; Ascoli, G ; Busnello, R ; Kienzle-Focacci, M N ; Kienzle, W ; Klanner, Robert ; Landsberg, L G ; Lebedev, A A ; Lechanoine-Leluc, C ; Lecomte, P et al.
The branching ratio A/sup -//sub 2/ to eta pi /sup -//A/sup -//sub 2/ to rho pi =0.22+or-0.03 (statistical error; systematic error +0.02) has been measured at 40 GeV/c. From an analysis of the decay angular distribution a J/sup P/=2/sup +/ wave in a pure mod M mod =1 state, produced by natural parity exchange is obtained. [...]

Spin-parity analysis of the n pi /sup +/ system produced in the reaction pi /sup +/p to pi /sup +/ pi /sup +/n at 16 GeV/c / Sotiriou, D (CERN)
A spin-parity analysis of the n pi /sup +/ system produced in the reaction pi /sup +/p to pi /sup +/ pi /sup +/n at 16 GeV/c has shown that apart from the mass enhancements associated with the known resonances Delta /sup +/(1238), N*(1520) and N*(1688), there is an enhancement peaked at M(n pi /sup +/) approximately=1.35 GeV, approximately 0.2 GeV wide. For masses below M(n pi /sup +/) approximately=1.35 GeV this enhancement is predominantly due to J/sup P/=1/2/sup -/ states, while above, the J/sup P/=1/2/sup +/ states predominate. [...]

Resonance production in two photon collisions at LEP with the L3 detector / Andreev, V P (Dept of Phys & Astron)
The ee to eeK/sub S//sup 0/K/sup +or-/ pi /sup -or+/, ee to ee eta pi /sup +/ pi /sup -/ and e/sup +/e/sup to /e/sup +/e/sup -/ pi /sup +/ pi /sup -/ pi /sup +/ pi /sup -/ final states are studied with the L3 detector at LEP using data collected at center-of-mass energies from 160 GeV up to 202 GeV. The mass spectrum of the K/sub S//sup 0/K/sup +or-/ pi /sup -or+/ final state shows an enhancement around 1470 MeV, which is identified with the pseudoscalar meson eta (1440). [...]

Spin-parity structure of the (K pi pi )/sup 0/ system produced in the charge-exchange reaction K/sup -/p to (K/sup 0/ pi /sup +/ pi /sup -/) n at 42 GeV/c / Vergeest, J S M ; Cerrada, M ; Chaloupka, V ; Engelen, J J ; Gavillet, P ; Gay, J B ; Hemingway, R J ; Jongejans, B ; Kittel, E W ; Losty, Michael J et al.
A partial wave analysis of the K/sup 0/ pi /sup +/ pi /sup -/ system produced in the charge exchange reaction K/sup -/p to (K/sup 0/ pi /sup +/ pi /sup -/)n at 4.2 GeV/c has been performed both as a function of K pi pi mass and of t'. The 1/sup +/S wave forms the largest contribution to the K pi pi system and peaks at roughly the same mass as the Q in diffractive K pi pi production. [...]
