Multichannel calculation of D*s vector states and the D+sJ(2632) resonance.

Eef van Beveren1, George Rupp.   

Abstract

We study bound states below threshold and resonances above threshold in the D0K+ and D(+)(s)eta systems, using a many-coupled-channel model for nonexotic meson-meson scattering applied to states with the quantum numbers of cs quark-antiquark vector mesons. We fit the ground state at 2.112 GeV, whence the lowest resonances in D0K+ 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(s)eta than in D0K+, 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(+)(sJ)(2632) resonance. Therefore, we conclude that the D(+)(sJ)(2632) is probably the first recurrence of the D(*)(s)(2112) meson.
