| Résumé : | The reaction K-d→K-π+π-d has been studied at an incident K--momentum of 4.5 GeV/c. A fractional analysis has been performed. A spin density matrix analysis and a partial wave analysis indicate that the events in the Q-region mainly originate from {Mathematical expression} production in a JPℓmη=(1+S0+) wave state. A comparison has been made with the reaction K+d→K+π-π+d at 4.6 GeV/c and the combined results have been compared to K+/-p→K+/-π+π-p at 13 GeV/c. It is found that the Kππ-mass spectra produced on a proton or deuteron target can be described by one single Deck type mechanism on which direct Q-meson production is superimposed. © 1980 Springer-Verlag. |
