我们证明了超膜中无质量粒子的存在。它们发生在完全坍塌的薄膜的扇区，由于超对称性，真空能量为零。只有在11维的超膜中，无质量状态包括一个引力子。因此，在临界维度d=11中，无质量粒子对应于超重力多重态。我们还发现，超膜外伸展程度较高的物体不存在出现超重力多重的临界维度。
We show the existence of massless particles in the supermembrane. These occur in the sector of a completely collapsed membrane and receive zero vacuum energy thanks to supersymmetry. Only in the 11-dimensional supermembrane the massless states include a graviton. Thus, in the critical dimension d = 11 the massless particles correspond to the supergravity multiplet. We also find that higher extended objects beyond the supermembrane have no critical dimension in which the supergravity multiplet emerges.
