Homotopy Operators and Identity-Based Solutions in Cubic Superstring Field Theory

High Energy Physics - Theory 2015-05-30 v1

Abstract

We construct a class of nilpotent operators using the BRST current and ghost fields in superstring theory. The operator can be realized in cubic superstring field theory as a kinetic operator in the background of an identity-based solution. For a particular type of the deformed BRST operators, we find a homotopy operator and discuss its relationship to the cohomology in a similar way to the bosonic case, which has been elaborated by the authors.
