Charmed scalar resonances -- Conventional and four-quark mesons
arXiv:hep-ph/0501188 · doi:10.1143/PTP.114.205
Abstract
We propose that there coexist two scalar mesons of different structures (a conventional meson and a four-quark meson) in the recently observed broad bumps just below the large peak of the tensor meson in the D-pi mass distribution. We base this proposal on the interpretation of the charm-strange scalar meson of mass 2317 MeV as a four-quark meson. The strange counterparts of these scalar mesons are also studied.
