Tensor form factors of decuplet hyperons in QCD

Year: 2026

Type: article

Abstract: Tensor form factors encode essential information about the internal spin structure and tensor dynamics of baryons. In this work, we investigate the tensor form factors of the baryon hyperons Ω − , Σ * + , and Ξ * − within the framework of QCD sum rules. The complete set of tensor form factors is numerically evaluated in the momentum transfer region 0 < Q 2 < 10 GeV 2 . In addition, the quark tensor charges of the considered hyperons are extracted in the forward limit. The results provide new nonperturbative insight into the tensor structure and spin content of spin- 3 / 2 baryons and offer valuable theoretical input for future phenomenological analyses and experimental studies.
