在弦论中，标量场通常表现为D-膜在高维空间中的几何构型的模。在D膜的低能有效理论中，D膜之间的距离被转化为规范对称性破缺的能量标度。在这篇文章中，我们研究了这样一种可能性的唯象结果，即希格斯场就是这样一个模场，而D膜的构型是通过静止运动，特别是我们赖以生存的D膜的旋转来稳定的。然后，由于科里奥利力的作用，希格斯模与薄膜的角涨落混合在一起，破坏了希格斯玻色子色散关系中的洛伦兹对称性。大型强子对撞机实验中的希格斯玻色子质量测量给出了D-膜自转角频率的上限GeV。
In string theory, a scalar field often appears as a moduli of a geometrical configuration of D-branes in higher-dimensional space. In the low energy effective theory on D-branes, the distance between D-branes is translated into the energy scale of the gauge symmetry breaking. In this paper, we study a phenomenological consequence of a possibility that the Higgs field is such a moduli field and the D-brane configuration is stabilized by a stationary motion, in particular, revolution of D-branes on which we live. Then, due to the Coriolis force, Higgs mode is mixed with the angular fluctuation of branes and the Lorentz symmetry is violated in the dispersion relation of the Higgs boson. The Higgs boson mass measurements at LHC experiments give an upper boundGeV for the angular frequency of the revolution of D-branes.
