Integrated Massive Vertex Operator in Pure Spinor Formalism

Abstract

We construct the integrated vertex operator for the first massive states of open superstrings with $(mass{)}^2=1/{\alpha }^{\prime }$ in the pure spinor formalism of the superstring theory. This vertex operator is expressed in terms of the ten dimensional $\mathcal{N}=1$ superfields describing the massive supermultiplet which appear in the unintegrated vertex operator of the same states.
