13 May 2004 | Subject: | hep-ph | Affiliation: | Institute of High Energy Physics, Beijing), D.V.Bugg (QMC, London | Abstract: | A correct understanding and description of the I=2 pi-pi S-wave interaction is important for the extraction of the I=0 pi-pi S-wave interaction from experimental data and for understanding the I=0 pi-pi S-wave interaction theoretically. With t-channel rho, f2(1270) exchange and the pi pi -> rho rho -> pi pi box diagram contribution, we reproduce the pi-pi isotensor S-wave and D-wave scattering phase shifts and inelasticities up to 2.2 GeV quite well in a K-matrix formalism. | Source: | arXiv, hep-ph/0405118 | Services: | Forum | Review | PDF | Favorites |
