Observed Ds(2317) and tentative D(2100-2300) as the charmed cousins of the light scalar nonet.

The very recently observed D(*)(sJ)(2317)(+) meson is described as a quasibound scalar csmacr; state in a unitarized meson model, owing its existence to the strong 3P0 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… CONTINUE READING
