AdS/QCD软壁模型中的手征对称性破缺

Chiral Symmetry Breaking in a Soft-Wall Model of AdS/QCD

Joseph I. Kapusta, Thomas M. Kelley, Tony Gherghetta

摘要:

我们在AdS/QCD模型的软壁模型中引入了手征对称性破缺,并在体标量势中引入了一个修正的声子轮廓和一个四次项。这使得人们能够分离自发和明确的手征对称性破缺的依赖性。在标量,矢量和轴向矢量部门产生的质谱比较有利的QCD共振。

英文摘要:

We incorporate chiral symmetry breaking in a soft-wall version of the AdS/QCD model by using a modified dilaton profile and a quartic term in the bulk scalar potential. This allows one to separate the dependence on spontaneous and explicit chiral symmetry breaking. The resulting mass spectra in the scalar, vector and axial-vector sectors compares favorably with the respective QCD resonances.
