Assuming Yb(10890) as a P-wave bq-scalar-diquark ¯b ¯q-scalar-antidiquark
tetraquark state, the mass of Yb(10890) is computed in the framework of QCD sum rule
method. Technically, contribu...

In this article, we assume that the Ds(2700) is a tetraquark state, which consists of a scalar diquark and a vector antidiquark, and calculate its mass with the QCD sum rules. The numerical result ind...

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...
