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<Q2<10  GeV2. 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.
