外尔不变量Dirac-Born-Infeld-Einstein理论

Weyl invariant Dirac-Born-Infeld-Einstein theory

Nahomi Kan, Takuya Maki, Kiyoshi Shiraishi

摘要:

我们考虑Dirac-Born-Infeld型引力的Weyl不变扩展。度量的适当选择隐藏了标量自由度,这是初看起来作用的局部尺度不变性所要求的,然后向量场获得了质量。此外,非最小耦合的向量场和曲率的诱导,这可能是适合的向量膨胀的情况。

英文摘要:

We consider a Weyl invariant extension of Dirac-Born-Infeld type gravity. An appropriate choice of the metric hides the scalar degree of freedom which is required by the local scale invariance of the action at the first sight, and then a vector field acquires mass. Moreover, nonminimal couplings of the vector field and curvatures are induced, which may be suitable to the vector inflation scenario.
