We study the possible tetraquark interpretation of light scalar meson states a0(980), f0(980), κ,σ within the framework of the non-relativistic potential model. The wave functions of tetraquark states are obtained in a space spanned by 相似文献

We study possible exotic JPC=0+- states using tetraquark interpolating currents with the QCD sum rule approach. The extracted masses are around 4.85GeV for the charmonium-like states and 11.25 GeV for the bottomonium-like states. There is no working region for the light tetraquark currents, which implies that the light 0+- state may not exist below 2GeV. 相似文献

In a previous work, we proposed an extended Nmnbu-Jona-Lasinio (NJL) model including heavy quark flavors. In this work, we will calculate strong and radiative decays of vector mesons in this extended NJL model, including light p, w, K*, θ and heavy D*, D*s, B*, Bs*. 相似文献

The Babar Collaboration announced two new excited charmed baryons Ξc(3055)+ and Ξc(3123)+. We study their strong decays assuming they are D-wave states. Some assignments are excluded by comparing our numerical results with the experimental values of the total widths of Ξc(3055)+ and Ξc(3123)+. We also suggest some possible decay modes, which will be helpful to 相似文献
