用约束类BF理论表示的Yang-Mills问题的纯Dirac方法

A pure Dirac's method for Yang-Mills expressed as a constrained BF-like theory

Alberto Escalante, Jasel Berra

摘要:

一个纯粹的狄拉克方法的杨米尔斯表示为一个约束BF类理论。本文研究由两个拓扑类BF理论耦合而成的作用量原理,它在拉格朗日水平上再现了Yang-Mills方程。通过纯狄拉克方法,我们的意思是,我们认为所有的变量,发生在拉格朗日密度作为动力学变量,而不仅仅是那些涉及时间导数。在完备相空间中的分析使我们能够计算扩展的哈密顿量、扩展的作用量、约束代数、规范变换,然后进行自由度的计算。我们证明了约束类BF理论在经典水平上对应于杨-米尔斯理论。根据所得结果,我们简要地讨论了该理论的量子化。此外,我们比较我们的结果与替代模型,已在文献中报道

英文摘要:

A pure Dirac's method of Yang-Mills expressed as a constrained BF-like theory is performed. In this paper we study an action principle composed by the coupling of two topological BF-like theories, which at the Lagrangian level reproduces Yang-Mills equations. By a pure Dirac's method we mean that we consider all the variables that occur in the Lagrangian density as dynamical variables and not only those ones that involve temporal derivatives. The analysis in the complete phase space enable us to calculate the extended Hamiltonian, the extended action, the constraint algebra, the gauge transformations and then we carry out the counting of degrees of freedom. We show that the constrained BF-like theory correspond at classical level to Yang-Mills theory. From the results obtained, we discuss briefly the quantization of the theory. In addition we compare our results with alternatives models that have been reported in the literature
