开超弦场论的Witten和Berkovits表述中约化结构和主作用量之间的关系

Relation between the Reducibility Structures and between the Master Actions in the Witten Formulation and the Berkovits Formulation of Open Superstring Field Theory

Yuki Iimori, Shingo Torii

摘要:

本作者等人在JHEP 03(2014)044 [arXiv:1312.1677]中开发分析,本文在主作用量水平上,即在Batalin-Vilkovisky形式主义中经典主方程的解的水平上,阐明了开超弦场论的Witten形式和Berkovits形式之间的关系,这是路径积分量子化的关键。我们首先仔细检查约化结构,一个详细的规范结构包含有关鬼弦场的信息。然后,将上述文献中部分规范固定的条件推广到鬼弦场的扇区,研究了主作用量。我们证明了Berkovits公式在部分规范固定下的约化结构和主作用量可以看作是Witten公式的正则化形式。

英文摘要:

Developing the analysis in JHEP 03 (2014) 044 [arXiv:1312.1677] by the present authors et al., we clarify the relation between the Witten formulation and the Berkovits formulation of open superstring field theory at the level of the master action, namely the solution to the classical master equation in the Batalin-Vilkovisky formalism, which is the key for the path-integral quantization. We first scrutinize the reducibility structure, a detailed gauge structure containing the information about ghost string fields. Then, extending the condition for partial gauge fixing introduced in the above-mentioned paper to the sector of ghost string fields, we investigate the master action. We show that the reducibility structure and the master action under partial gauge fixing of the Berkovits formulation can be regarded as the regularized versions of those in the Witten formulation.
