AI 中文摘要
我们在两种全息设置中研究核子谱:爱因斯坦-伸缩子引力模型和Starobinsky-伸缩子引力模型。爱因斯坦-伸缩子全息模型,又称改进的全息QCD,早前被提出用于描述禁闭和胶球谱,近期已应用于介子和核子的研究。本研究重新审视爱因斯坦-伸缩子全息模型,引入新参数以提升与实验数据的对比效果;随后将该思路拓展至Starobinsky-伸缩子引力领域,构建另一改进全息模型,用其重新分析核子谱,并与软壁模型及实验数据进行对比。
英文摘要
We study the nucleon spectra in two holographic set-ups: Einstein-dilaton and Starobinsky-dilaton gravity models. The Einstein-dilaton holographic model, also known as improved holographic QCD, have been proposed some time ago to describe confinement and glueball spectra. Recently, it has been applied to the case of mesons and nucleons. In this work, we reconsider the Einstein-dilaton holographic model to discuss the nucleon spectra introducing new parameters that allow us to improve the comparison with experimental data. Then, we extend this idea to the context of Starobinsky-dilaton gravity defining another improved holographic model. We use this new holographic model to reanalyse the nucleon spectra and also compare them with soft-wall model and experimental data.
