论文摘要
我们得出并分析了康奈尔类型在广义软壁全息模型框架内的限制潜力，该模型包括控制线性regge频谱的截距的参数。在Regge轨迹的现象学中，此参数对于实验数据的定量描述非常重要。我们的分析表明，在标量通道中获得的“线性加库仑”的限制潜力在定量上与现象学和晶格模拟一致，而矢量通道中的一致性仅是定性的。该结果表明真空标量扇区在形成限制电位中的关键作用。作为副产品，我们对禁闭潜力的全息描述的总体一致性似乎证实了标量介子$ f_0（1500）$的粘合球性质。
We derive and analyze the confinement potential of the Cornell type within the framework of the generalized Soft Wall holographic model that includes a parameter controlling the intercept of the linear Regge spectrum. In the phenomenology of Regge trajectories, this parameter is very important for the quantitative description of experimental data. Our analysis shows that the ''linear plus Coulomb'' confinement potential obtained in the scalar channel is quantitatively consistent with the phenomenology and lattice simulations while the agreement in the vector channel is qualitative only. This result indicates the key role of the vacuum scalar sector in the formation of the confinement potential. As a by-product the overall consistency of our holographic description of confinement potential seems to confirm the glueball nature of the scalar meson $f_0(1500)$.
