标题： SUSY Gauge Dynamics and Singularities of 4d N=1 String Vacua

摘要： 许多N=1杂化弦紧致化在真空模空间的一维余维处表现出物理上神秘的奇点。 在这些奇点处，带电场的Yukawa耦合作为模参数的函数出现极点。 我们通过一些例子解释这些共形场论奇点，它们来源于弦理论中非微扰规范玻色子的非微扰规范动力学（其规范耦合是sigma模型耦合）。 显示英文摘要

摘要： Many N=1 heterotic string compactifications exhibit physically mysterious singularities at codimension one in the moduli space of vacua. At these singularities, Yukawa couplings of charged fields develop poles as a function of the moduli. We explain these conformal field theory singularities, in a class of examples, as arising from non-perturbative gauge dynamics of non-perturbative gauge bosons (whose gauge coupling is the sigma model coupling) in the string theory.
