包含介子的手征尺度有效理论

Chiral-scale effective theory including a dilatonic meson

Yan-Ling Li, Yong-Liang Ma, Mannque Rho

摘要:

本文构造了八重态π介子和一个八重态π介子的标度不变手征有效拉格朗日量,它们都是Nambu-Goldstone玻色子,矢量介子作为隐规范场.在没有重子场的情况下,拉格朗日量被建立到手征尺度计数的次领先阶,然后建立到包括重子的领先阶。由此产生的理论是隐藏的规模对称和局部对称。我们还讨论了一些可能的应用,目前拉格朗日。

英文摘要:

A scale-invariant chiral effective Lagrangian is constructed for octet pions and a dilaton figuring as Nambu-Goldstone bosons with vector mesons incorporated as hidden gauge fields. The Lagrangian is built to the next-to-leading order in chiral-scale counting without baryon fields and then to leading order including baryons. The resulting theory is hidden scale-symmetric and local symmetric. We also discuss some possible applications of the present Lagrangian.
