Some Remarks About Berkovits' Superstring Field Theory

Abstract

In this short note we would like to discuss general solutions of the Berkovits superstring field theory, in particular the string field action for fluctuation around such a solution. We will find that fluctuations obey the same equation of motion as the original field with the new BRST operator. Then we will argue that the superstring field theory action for fluctuation field has the same form as the original one.
