摘要:

本文研究了规范场中具有高阶导数项的十维Yang-Mills理论中的涨落模。我们认为十维时空是一个四维时空和六维球面的乘积,表现出动力学紧化。由于S^6上的等距性,在关于该解的有效理论中,存在对应于南武-戈德斯通零模的平坦方向。零模被吸收到规范场中,并作为希格斯-基布尔机制的结果形成大质量矢量场。矢量场的质量与球体半径的倒数成正比,并且由于高阶导数项而大于半径设定的质量标度。

英文摘要:

We study fluctuation modes in ten-dimensional Yang-Mills theory with a higher derivative term for the gauge field. We consider the ten-dimensional space-time to be a product of a four-dimensional space-time and six-dimensional sphere which exhibits dynamical compactification. Because of the isometry on S^6, there are flat directions corresponding to the Nambu-Goldstone zero modes in the effective theory on the solution. The zero modes are absorbed into gauge fields and form massive vector fields as a consequence of the Higgs-Kibble mechanism. The mass of the vector fields is proportional to the inverse of the radius of the sphere and larger than the mass scale set by the radius because of the higher derivative term.
