标题： S-Duality and the Spectrum of Magnetic Monopoles in Heterotic String Theory

摘要： 我们讨论了S对偶性对于由环面紧致化导致的四维异弦理论单极谱的预言。 我们详细讨论了"H-单极子"的谱，这些状态相对于从十维反对称张量场降维得到的U(1)群具有磁荷。 利用关于弦理论中集体坐标处理方式的假设，我们得到了与S对偶性一致的结果。 显示英文摘要

摘要： We discuss the predictions of S-duality for the monopole spectrum of four-dimensional heterotic string theory resulting from toroidal compactification. We discuss in detail the spectrum of "H-monopoles", states that are magnetically charged with respect to the U(1) groups arising from the dimensional reduction of the ten dimensional antisymmetric tensor field. Using an assumption concerning the correct treatment of collective coordinates in string theory we find results which are consistent with S-duality.
