Analysis of the X(1576) as a tetraquark state with the QCD sum rules

Zhi-Gang Wang, Shao-Long Wan

In this letter, we take the point of view that the X(1576) be tetraquark state which consists of a scalar-diquark and an anti-scalar-diquark in relative $P$ -wave, and calculate its…

Structures of the $f_{0} (980)$ , $a_{0} (980)$ mesons and the strong coupling constants $g_{f_{0} K^{+} K^{-}}$ , $g_{a_{0} K^{+} K^{-}}$ with the light-cone QCD sum rules

Zhi-Gang Wang, Wei-Min Yang, Shao-Long Wan

In this article, with the assumption of explicit isospin violation arising from the $f_{0} (980) - a_{0} (980)$ mixing, we take the point of view that the scalar mesons $f_{0} (980)$ and $a_0…

Studying the Bell--Steinberger relation

K. Urbanowski

The Bell--Steinberger relation is analyzed. The questionable points of the standard derivation of this relation are discussed. It is shown that the use of a more accurate approxima…
