摘要

利用带热膨胀场的全息软壁模型研究了有限温度下核子的轴矢量形状因子。我们使用从零温度情况中已知的体相互作用，并应用由与热膨胀场相互作用而热化的场的剖面函数。对于核子的基态和激发态，轴向形状因子对传递动量和温度的平方的依赖关系被绘制出来。

Axial-vector form factor of nucleons at finite temperature from the AdS/QCD soft-wall model

The axial-vector form factor of the nucleons is studied at a finite temperature using the holographic soft-wall model with the thermal dilaton field. We use the bulk interaction action known from the zero temperature case and apply the profile functions of fields thermalized by the interaction with the thermal dilaton field. The dependence of the axial form factor on the square of the transferred momentum and the temperature is plotted for the ground and excited states of the nucleons.
