Decays of Dsj*(2317) and Dsj(2460) Mesons in the Quark Model

  • We study the decay widths of the narrow resonances Dsj*(2317) and Dsj(2460) in the chiral quark model, together with the well-known D* and Ds* mesons. All the parameters in our calculation are taken from Godfrey and Isgur's quark model except the π0-η mixing angle which is fixed by the Ds* decay widths. The calculated electromagnetic decay widths agree with those from other groups and the experimental data available quite well. However, the pionic decay widths of Dsj(2317) and Dsj(2460) are too small to fit the experimental data. We suspect that the simple chiral quark pion axial-vector interaction Hamiltonian is not suitable for hadron strong decays of Dsj(2317) and Dsj(2460).

Abstract: We study the decay widths of the narrow resonances Dsj*(2317) and Dsj(2460) in the chiral quark model, together with the well-known D* and Ds* mesons. All the parameters in our calculation are taken from Godfrey and Isgur's quark model except the π0-η mixing angle which is fixed by the Ds* decay widths. The calculated electromagnetic decay widths agree with those from other groups and the experimental data available quite well. However, the pionic decay widths of Dsj(2317) and Dsj(2460) are too small to fit the experimental data. We suspect that the simple chiral quark pion axial-vector interaction Hamiltonian is not suitable for hadron strong decays of Dsj(2317) and Dsj(2460).
