DOI: 10.1088/1674-1137/43/12/123102
Abstract: In this article, we take the scalar diquark and antidiquark as the basic constituents, construct the $C\gamma_5\otimes\stackrel{\leftrightarrow}{\partial}_\mu\otimes \gamma_5C$ type tetraquark current to study the $Y(10750)$ with the QCD sum rules. The predicted mass $M_{Y}=10.75\pm0.10\,\rm{GeV}$ supports… read more here.

DOI: 10.1103/physrevd.105.054018
Abstract: Open-heavy tetraquark states, especially those contain four different quarks have drawn much attention in both theoretical and experimental fields. In the framework of the improved chromomagnetic interaction (ICMI) model, we complete a systematic study on… read more here.
