洛伦兹破坏和希格斯机制

Lorentz Violation and the Higgs Mechanism

Brett Altschul

摘要:

我们考虑在希格斯相和洛伦兹破坏的存在下的标量量子电动力学。规范对称性的自发破缺产生了洛伦兹破坏的规范场质量项。这可能导致规范场的纵模超光速传播。这个理论可以用Faddeev-Popov方法量子化,尽管鬼场的拉格朗日量也需要是洛伦兹破坏的。

英文摘要:

We consider scalar quantum electrodynamics in the Higgs phase and in the presence of Lorentz violation. Spontaneous breaking of the gauge symmetry gives rise to Lorentz-violating gauge field mass terms. These may cause the longitudinal mode of the gauge field to propagate superluminally. The theory may be quantized by the Faddeev-Popov procedure, although the Lagrangian for the ghost fields also needs to be Lorentz violating.
