论文摘要
我们根据Mandelstam的相互作用的字符串图片,提出了Witten开放式弦字段理论的脱壳场变量与Kaku和Kikkawa的传统LightCone字段理论之间的转换。这是通过将Witten顶点变形为LightCone立方和四分之一顶点来完成的,然后将其从字符串字段中整合到幽灵和灯酮的振动激发。令人惊讶的是,最后一步不会改变立方体和四分之一的相互作用,也不会产生有效的顶点,并确切地导致了Kaku和Kikkawa的LightCone弦乐场理论。
We propose a transformation between the off-shell field variables of Witten's open bosonic string field theory and the traditional lightcone string field theory of Kaku and Kikkawa, based on Mandelstam's interacting string picture. This is accomplished by deforming the Witten vertex into lightcone cubic and quartic vertices, followed by integrating out the ghost and lightcone oscillator excitations from the string field. Surprisingly, the last step does not alter the cubic and quartic interactions and does not generate effective vertices, and leads precisely to Kaku and Kikkawa's lightcone string field theory.
