Analysis of the scalar and axial-vector heavy diquark states with QCD sum rules
read the original abstract
In this article, we study the mass spectrum of the scalar and axial-vector heavy diquark states with the QCD sum rules in a systematic way. Once the reasonable values are obtained, we can take them as basic parameters and study the new charmonium-like states as the tetraquark states.

Deciphering the nature of $P^{\Sigma}_{\psi s}$ pentaquarks in the light of their electromagnetic multipole moments
Electromagnetic moments of Σ-type pentaquarks are computed via light-cone sum rules, yielding flavor-sensitive magnetic dipoles, quadrupoles, and octupoles that distinguish diquark types and rule out S-wave molecules.
