We begin by identifying the beta deformation as states living in a specific irreducible representation of the superconformal algebra. Then, we compute the ghost number two elements of the BRST cohomology of the topological model. A gauge-fixing procedure is applied to these states, allowing us to identify the elements living in the irreducible representation that characterizes the beta deformation. Based on this identification, we proceed to write the deformed topological action, and the corresponding deformed BRST operator. (AU)
