摘要:

本文在硬壁AdS/QCD模型框架下研究了氘核的电磁形状因子和张量极化观测量。我们找到了一个描述边界上氘核的体扭转$τ=6$矢量场的轮廓函数,并根据氘核的基态质量确定了AdS空间的红外边界截止。我们得到的氘核电荷的双极,四极,和磁偶极子形状因子和张量极化观测量的氘核和光子场相互作用的体拉格朗日。我们绘制了形状因子和张量偏振观测量的动量传递依赖关系,并将我们的数值结果与软壁模型和实验数据进行了比较。

英文摘要:

We study the electromagnetic form factors and tensor polarization observables of the deuteron in the framework of the hard-wall AdS/QCD model. We find a profile function for the bulk twist $τ=6$ vector field, which describes the deuteron on the boundary and fix the infrared boundary cut-off of AdS space in accordance with the ground state mass of the deuteron. We obtain the deuteron charge monopole, quadrupole, and magnetic dipole form factors and tensor polarization observables from the bulk Lagrangians for the deuteron and photon field interactions. We plot the momentum transfer dependence of the form factors and tensor polarization observables and compare our numerical results with those in the soft-wall model and experimental data.
