利用超弦理论和大N规范理论之间的对偶性，计算了三维和四维非超对称Yang-Mills理论中胶球质量的谱.超引力的卡鲁扎·克莱因态不对应于杨-米尔斯理论中的任何态，因此在连续极限下应该解耦。另一方面，在超引力极限g}MN -700，我们发现Kaluza-Klein态的质量与胶球的质量相当。我们还表明，领先的（g}MN）-l修正并没有使这些国家比胶球重。因此，Kaluza-Klein态的退耦对这个顺序并不明显。
Spectra of glueball masses in non-supersymmetric Yang-Mills theory in three and four dimensions have recently been computed using the conjectured duality between superstring theory and large N gauge theory. The Kaluza Klein states of supergravity do not correspond to any states in the Yang-Mills theory and therefore should decouple in the continuum limit. On the other hand, in the supergravity limit g}MN --7 00, we find that the masses of the Kaluza-Klein states are comparable to those of the glueballs. We also show that the leading (g}MN)-l corrections do not make these states heavier than the glueballs. Therefore, the decoupling of the Kaluza-Klein states is not evident to this order.
