论文摘要
在本文中，在有限温度限制下，已在ADS/QCD软壁模型中研究了Meson- $Δ$ BARYON和MESON-NUCLEON至$δ$ BARYON转变的最小耦合常数。最初，在此模型中使用Rarita-Schwinger字段计算了$Δ$ BARYON的左右配置文件功能。此后，通过根据零温度的情况来考虑热辐射的曲线功能来编写耦合常数。然后，为强耦合绘制温度依赖图$ g_ {ρΔδ}（t）$，$ g_ {a_ {1} a_ {1}ΔΔ}（t）$和$ g_ {ρnΔ}（t）$。结果，已经通过温度升高来观察到，最小耦合常数的值降低并接近鹰温度的零。
In this paper, minimal coupling constants of meson-$Δ$ baryon and meson-nucleon to $Δ$ baryon transition have been investigated in the AdS/QCD soft-wall model at finite temperature limits. Initially, the right and left profile functions of $Δ$ baryons have been calculated using the Rarita-Schwinger field in this model. After this, coupling constants have been written by taking into account the profile functions of thermal hadrons according to the zero-temperature case. Then, the temperature dependence graphs are plotted for strong couplings $g_{ρΔΔ}(T)$, $g_{a_{1} ΔΔ}(T)$ and $g_{ρN Δ}(T)$. As a result, it has been observed by an increase in the temperature, values of the minimal coupling constants decreased and approached zero nearby Hawking temperature.
