THE JP = 2+ DIBARYON IN πNN CALCULATION OF pp→π+ pn PROCESS
T. UEDAFaculty of Engineering Science, Osaka University, Toyonaka, Osaka 560, Japan
Résumé
Pour la réaction pp→π+ pn à Ep = 400 - 1000 MeV, l'amplitude théorique JP = 2+ issue de la dynamique πNN fait une boucle de sens direct dans le diagramme d'Argand, ce qui suggère l'existence possible de dibaryon JP = 2+.
Abstract
For pp→π+ pn reaction at Elab = 400 - 1000 MeV the theoretical JP = 2+ amplitude due to the πNN dynamics makes an anticlockwise looping behavior in the Argand plot and provides an evidence in favour for the existence of the JP = 2+ dibaryon.
