标量与规范场的反常耦合

Anomalous coupling of scalars to gauge fields

Philippe Brax, Clare Burrage, Anne-Christine Davis, David Seery, Amanda Weltman

摘要:

我们研究的标量张量理论,耦合到费米子,下的Weyl重新标度与从约旦到爱因斯坦框架的过渡。我们给出了一个简单的推导相应的修改规范耦合。变换标架后,标量场与规范场之间产生直接耦合。

英文摘要:

We study the transformation properties of a scalar-tensor theory, coupled to fermions, under the Weyl rescaling associated with a transition from the Jordan to the Einstein frame. We give a simple derivation of the corresponding modification to the gauge couplings. After changing frame, this gives rise to a direct coupling between the scalar and the gauge fields.
