我们计算了在有磁通的环面上压缩的六维Yang-Mills理论中标量场零模质量的单圈修正。结果表明，由于额外空间平移下的平移对称性，这些修正被精确地抵消了。这一结果是由于标量场的零模是额外空间中平移不变性的Nambu-Goldstone玻色子这一事实而得到的。
We calculate one-loop corrections to the mass for the zero mode of scalar field in a six-dimensional Yang-Mills theory compactified on a torus with magnetic flux. It is shown that these corrections are exactly cancelled thanks to a shift symmetry under the translation in extra spaces. This result is expected from the fact that the zero mode of scalar field is a Nambu-Goldstone boson of the translational invariance in extra spaces.
