具有手征对称性破缺的波前全息术

Light-front holography with chiral symmetry breaking

Yang Li, James P. Vary

摘要:

我们提出了一个解析可解的三维强子光阵面哈密顿模型,通过引入有限质量夸克和纵向约束项扩展了光阵面全息。我们建议,该模型是适合作为一个改进的解析近似QCD在低分辨率尺度。我们证明,它保留了所需的洛伦兹对称性,它产生了改进的协议与实验质谱和轻介子的其他属性。重要的是,该模型还尊重手征对称性和盖尔曼-奥克斯-伦纳关系。

英文摘要:

We present an analytically solvable 3D light-front Hamiltonian model for hadrons that extends light-front holography by including finite mass quarks and a longitudinal confinement term. We propose that the model is suitable as an improved analytic approximation to QCD at a low resolution scale. We demonstrate that it preserves desired Lorentz symmetries and it produces improved agreement with the experimental mass spectroscopy and other properties of the light mesons. Importantly, the model also respects chiral symmetry and the Gell-Mann-Oakes-Renner relation.
