Complete Action for Open Superstring Field Theory

Abstract

In formulating superstring field theory, construction of an action including the Ramond sector has not been successful for about thirty years, and this has been a major obstacle. Last year, a gauge-invariant action was constructed for open superstring field theory including both the Neveu-Schwarz sector and the Ramond sector. This is the first construction of a complete formulation of superstring field theory. In this talk, the speaker will explain the construction of the complete action without assuming any background on string field theory. The talk is based on the paper arXiv:1508.00366 in collaboration with KUNITOMO.
