Abstract
We construct the integrated vertex operator for the first massive states of open superstrings with (mass)2 = 1/α′ 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.
