我们最近证明了(3， + ，1)维膨胀宇宙从洛伦兹版本的IIB矩阵模型看起来是动态的和唯一的，该模型被认为是超弦理论的非微扰形式。同样，标准模型也有可能在后期从同一模型唯一地出现在电弱尺度上。为了追求这种可能性，我们讨论了如何推导出同一公式中后期出现的无质量模的有效局域场理论。作为一个具体的例子，我们考虑了与(9 + 1)维Poincaré对称性和超对称性自发破缺相关的无质量模。
We have recently shown that a (3 + 1)-dimensional expanding universe appears dynamically and uniquely from the Lorentzian version of the IIB matrix model, which is considered as a nonperturbative formulation of superstring theory. Similarly, it is possible that the Standard Model appears uniquely at the electroweak scale from the same model at late times. In order to pursue such a possibility, we discuss how to derive the effective local field theory for the massless modes that appear at late times in the same formulation. As a concrete example, we consider the massless modes associated with the spontaneous breaking of (9 + 1)-dimensional Poincaré symmetry and supersymmetry.
