Light scalar mesons as tetraquarks within QCD Sum Rules
Hee-Jung Lee
We examine the interpretation of the light scalar meson nonet as tetraquark states using QCD sum rules. With the interpolating current for the tetraquark states composed of scalar…

On the contribution to the QCD sum rules for the light tetraquark
Hee-Jung Lee, N. I. Kochelev
We perform a QCD sum rule analysis for the light tetraquark taking into account the contribution arising from the two pion intermediate state. With the interpolating currents…
