On the Pure Spinor Heterotic Superstring $b$ Ghost

Abstract

A simplified pure spinor superstring $b$ ghost in a curved heterotic background was constructed recently. The $b$ ghost is a composite operator and it is not holomorphic. However, it satisfies $\bar{\partial }b=[Q,\Omega ]$, where $Q$ is the BRST charge. In this paper, we find a possible $\Omega$.
