讨论了将sym解解释为自旋自交额外维的新解。值得注意的是，这些背景导致了具有3代手性费米子耦合到标量场和规范场的低能扇区，具有标准的洛伦兹不变运动学。这个扇区是由定位在旋转轴上的零模式产生的，这与背景旋转无关。其余的模不是由洛伦兹不变场论描述的，而且大多是“重的”，但是有一个六重的速子激发。假设后者通过量子效应得到稳定，我们认为对于某些低能标量场，不同的旋转频率会诱发VEV。我们讨论了可能导致低能物理离标准模型的破缺相不远的构型。
New solutions ofSYM oninterpreted as spinning self-intersecting extra dimensions are discussed. Remarkably, these backgrounds lead to a low-energy sector with 3 generations of chiral fermions coupled to scalar and gauge fields, with standard Lorentz-invariant kinematics. This sector arises from zero modes localized on the rotation axes, which are oblivious to the background rotation. The remaining modes are not described by a Lorentz-invariant field theory and are mostly "heavy", but there is one sextet of tachyonic excitations. Assuming that the latter get stabilized e.g. by quantum effects, we argue that different rotation frequencies would induce a VEV for some of the low-energy scalar fields. We discuss configurations which may lead to a low-energy physics not far from the broken phase of the standard model.
