Título da revista, periódico, livro ou evento: | EPJ Web of Conferences | Volume: | 3 | Resumo: | In this manuscript we discuss about our study of the N ¯K and the N K systems made by solving the Faddeev equations with the two-body t-matrices obtained by solving the Bethe-Salpeter equations with the potentials obtained from chiral dynamics. In the strangeness = -1 case, we found that all the and resonances listed by the particle data group, with spin-parity 1/2+, in the 1550-1800 MeV region get generated due to the involved three-body dynamics. This motivated us to study the strangeness =1 three-body system, i.e., N K, where we did not find any evidence for the + (1542) but found a broad bump around 1700 MeV which has a (800)N structure. | URI: | https://hdl.handle.net/10316/110185 | ISSN: | 2100-014X | DOI: | 10.1051/epjconf/20100307016 | Direitos: | openAccess |
