Abstract
We study bound states below threshold and resonances above threshold in the D{sup 0}K{sup +} and D{sub s}{sup +}{eta} systems, using a many-coupled-channel model for nonexotic meson-meson scattering applied to states with the quantum numbers of cs-bar quark-antiquark vector mesons. We fit the ground state at 2.112 GeV, whence the lowest resonances in D{sup 0}K{sup +} come out at 2.61, 2.72, 3.03, and 3.08 GeV. The resonance at 2.61 GeV acquires a width of about 8 MeV, while its partial P wave cross section is up to 6 times larger in D{sub s}{eta} than in D{sup 0}K{sup +}, provided a mechanism accounting for Okubo-Zweig-Iizuka-forbidden decays is included. The latter finding is in agreement with the observations of the SELEX Collaboration with respect to the recently reported D{sub sJ}{sup +}(2632) resonance. Therefore, we conclude that the D{sub sJ}{sup +}(2632) is probably the first recurrence of the D{sub s}*(2112) meson.
