The QCD sum rule approach is used to analyze the nature of the recently observed new resonance X (4350), which is assumed to be a diquark-antidiquark state [cs][cs] with jPC = 1-+. The interpolating current represe...

We calculate the masses and decay constants of the P-wave strange-bottomed mesons Bs0 and Bs1 with the QCD sum rules, and observe that the central values of the masses Bs0 and Bs1 are smaller than the corresponding BK...

Based on a semi-classical expansion for quantum chromodynamics in the instanton liquid background, the correlation function of the 0^++ scalar glueball current is calculated. Besides the pure classical and quantum c...

In this article, we study the pentaquark state Θ+(1540) with a (scalar) diquark-(pseudoscalar) diquarkantiquark type interpolating current in the framework of the QCD sum rules approach by including the contri...
