自旋为3/2的重子的引力形状因子

Gravitational form factors of a baryon with spin-3/2

June-Young Kim, Bao-Dong Sun

摘要:

自旋为3/2的重子的能量动量张量(EMT)与\emph{seven}力学量有关。本文利用多极展开和EMT密度与引力形状因子之间的关系,给出了自旋为3/2的重子引力形状因子的一般形式。为了验证这些一般关系,我们研究了SU(2)Skyrme模型中基于大$N_{c}$极限的核子和$Δ$ GFF.

英文摘要:

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.
