Massive Superstring Vertex Operator in D=10 Superspace

TL;DR

This paper constructs a super-Poincaré covariant vertex operator for the first massive states of the open superstring in ten dimensions, describing a massive spin-two multiplet using superfields.

Contribution

It introduces a new vertex operator formalism for massive superstring states within the pure spinor framework, maintaining manifest supersymmetry.

Findings

Vertex operator describes a massive spin-two multiplet.

Constructed in a manifestly super-Poincaré covariant manner.

Provides a foundation for further superstring state analyses.

Abstract

Using the pure spinor formalism for the superstring, the vertex operator for the first massive states of the open superstring is constructed in a manifestly super-Poincar\'e covariant manner. This vertex operator describes a massive spin-two multiplet in terms of ten-dimensional superfields.
