本文研究了磁化环面上紧化的六维理论中规范场的额外维分量产生的标量零模。我们确认这是一个Nambu-Goldstone玻色子的平移对称的环面是自发破缺，由于磁通。我们还明确表明，它是无质量的两个循环的水平。此外，我们还讨论了考虑有效势的全阶贡献。
We study a scalar zero mode originated from extradimensional components of a gauge field in a six-dimensional theory compactified on a magnetized torus. We confirm it is a Nambu-Goldstone boson of the translational symmetry on the torus which is breaking spontaneously due to magnetic flux. We also show explicitly it is massless up to the two-loop level. Moreover, we discuss full order contributions by considering the effective potential.
