族规范对称性与Koide质量公式
Family Gauge Symmetry and Koide's Mass Formula
摘要:
小出氏质量公式是带电轻子质量之间的一个经验关系,它具有惊人的精确性。我们提出了一种机制,取消量子电动力学修正小出公式。这在一个具有U(3)族规范对称性的有效理论中讨论,并在10^2-10^3 TeV尺度下将这种对称性与SU(2)_L对称性统一起来。
英文摘要:
Koide's mass formula is an empirical relation among the charged lepton masses which holds with a striking precision. We propose a mechanism for cancelling the QED correction to Koide's formula. This is discussed in an effective theory with U(3) family gauge symmetry and a scenario in which this symmetry is unified with SU(2)_L symmetry at 10^2-10^3 TeV scale.
