Review of Open Superstring Field Theory

TL;DR

This paper reviews a construction of open superstring field theory action that avoids contact term issues, resembling a Wess-Zumino-Witten form, and maintains manifest D=4 super-Poincaré covariance.

Contribution

It presents a novel superstring field theory action formulation that overcomes contact term problems and preserves covariance.

Findings

Constructed a contact-term-free superstring field theory action.

The action is similar to a Wess-Zumino-Witten model.

Maintains manifest D=4 super-Poincaré covariance.

Abstract

I review the construction of an action for open superstring field theory which does not suffer from the contact term problems of other approaches. This action resembles a Wess-Zumino-Witten action and can be constructed in a manifestly D=4 super-Poincar\'e covariant manner. This review is based on lectures given at the ICTP Latin-American String School in Mexico City and the Komaba 2000 Workshop in Tokyo.
