Résumé
Pour la réaction pp→π⁺ pn à E_p = 400 - 1000 MeV, l'amplitude théorique J^P = 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 J^P = 2⁺.

Abstract
For pp→π⁺ pn reaction at E_lab = 400 - 1000 MeV the theoretical J^P = 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 J^P = 2⁺ dibaryon.
