Observed Ds(2317) and tentative D(2100-2300) as the charmed cousins of the light scalar nonet -: art. no. 012003

The very recently observed D-sJ(*)(2317)(+) meson is described as a quasibound scalar c (s) over bar state in a unitarized meson model, owing its existence to the strong P-3(0) Okubo-Zweig-Iizuka-allowed coupling to the nearby S-wave DK threshold. By the same mechanism, a scalar D-0(*)(2100-2300) resonance is predicted above the Dpi threshold. These scalars are the charmed cousins of the light scalar nonet f(0)(600), f(0)(980), K-0(*)(800), and a(0)(980), reproduced by the same model. The standard c (n) over bar and c (s) over bar charmed scalars D-0 and D-s0, cousins of the scalar nonet f(0)(1370), f(0)(1500), K-0(*)(1430), and a(0)(1450), are predicted to lie at about 2.64 and 2.79 GeV, respectively, both with a width of some 200 MeV.
