| 英文摘要 | We study the interaction of the D pi, D eta and D-s(K) over bar channels in J(P) = 0(+) in the framework of unitarized chiral perturbation theory in finite volume, predicting the volume dependence of the energy levels. The results succesfully describe the energy levels provided in a recent lattice QCD calculation of the same system. We find two poles in the energy region of the D-0*(2400) resonance, with masses 2105(-8)(+6), 2451(-26)(+36) MeV and half-widths 102(-12)(+10), 134(-8)(+7) MeV respectively. We study their evolution in the light-flavor SU(3) limit, which allows us to identify the D-s*(0)(2317) resonance and the pole with lower mass as partners of the same SU(3) multiplet. The mass of the higher pole is obtained between the D eta and D-s(K) over bar threshold energies, strongly coupled to the latter channel, thus we expect it to influence the D-s(K) over bar invariant mass distribution. |
