摘要

用软壁AdS/QCD模型研究了有限温度下JP=3/2+、JP=5/2+和JP=5/2−族的轻味重子共振,包括零温度极限。构建了将这些共振背后的构型熵与径向量子数和重子质量谱相关联的雷格轨迹,允许将高自旋轻味重子质量谱外推到更高的径向量子数值。在超过38mev的范围内,构型熵随温度急剧增加。对重子族的质谱进行了分析,支持相变几乎高于哈格多恩温度。

Higher-spin light-flavor baryonic spectroscopy in AdS/QCD at finite temperature
Light-flavor baryon resonances in the JP=3/2+, JP=5/2+, and JP=5/2 families are investigated in a soft-wall AdS/QCD model at finite temperature, including the zero temperature limit. Regge-like trajectories relating the configurational entropy underlying these resonances to both the radial quantum number and the baryon mass spectra are constructed, allowing for the extrapolation of the higher-spin light-flavor baryonic mass spectra to higher values of the radial quantum number. The configurational entropy is shown to increase drastically with temperature, in the range beyond 38 MeV. The mass spectra of baryon families are analyzed, supporting a phase transition nearly above the Hagedorn temperature.
