论文摘要
Spin-3/2 Baryon的能量量张量（EMT）与\ emph {七个}机械量有关。在这项工作中，我们通过使用EMT密度与GFF之间的多极扩展和有趣的关系，为Spin-3/2 Baryon提供重力形式因子（GFF）的一般形式。为了验证这些通用关系，我们根据大型$ n_ {C} $限制研究了SU（2）Skyrme模型中的核子和$δ$ GFF。
The energy-momentum tensor (EMT) for a spin-3/2 baryon is related to \emph{seven} mechanical quantities. In this work, we provide the general form of the gravitational form factors (GFFs) for a spin-3/2 baryon by using the multipole expansion and interesting relations between the EMT densities and the GFFs. To verify those general relations, we study the nucleon and the $Δ$ GFFs within the SU(2) Skyrme model based on the large $N_{c}$ limit.
