SO(4)/SO(3)对称破缺的Goldstone玻色子有效拉氏量的构造

Constructing Effective Lagrangians of the Goldstone Bosons of SO(4)/SO(3) Symmetry Breaking

    摘要
  • 摘要: 采用CCWZ方法和最近几年提出的移位对称性(Shift-symmetry)方法分别计算了SO(4)/SO(3) 对称破缺的Goldstone玻色子的有效拉氏量，并对2种方法的计算结果进行了对比. 研究表明：通过对Shift-symmetry方法构造的拉氏量中的自由参数f作f2f的标度变换，则用2种方法构造的有效拉氏量是一致的. 这证明了移位对称性方法在Goldstone玻色子有效拉氏量的构造方面的有效性.

     

    Abstract: With the CCWZ method and the recently proposed shift-symmetry method, the effective Lagrangians of Goldstone bosons of SO(4)/SO(3) symmetry breaking are separately constructed and the results are compared. It is shown that the effective Lagrangians constructed by rescaling the free parameter f with shift-symmetry method，f2f，are consistent. This proves the effectiveness of shift-symmetry method for the construction of effective Lagrangians of Goldstone bosons.
