描述了四维弦孤子（如Nielsen-Olesen涡旋或QCD弦）长距离动力学的有效共形场论。它是一个相互作用的庞加莱不变共形场论，有四个玻色子，{ital c}=26。这些天真的矛盾功能的兼容性，明确表明通过二阶微扰展开的长弦真空。
The effective conformal field theory governing the long-distance dynamics of string solitions in four dimensions, such as the Nielsen-Olesen vortex or QCD strings, is described. It is an interacting Poincare-invariant conformal field theory with four bosons and {ital c}=26. The compatibility of these naively contradictory features is explicitly demonstrated through second order in a perturbation expansion about the long-string vacuum.
