Covariant currents in N = 2 super-Liouville theory

Abstract: Based on a path integral prescription for anomaly calculation, we analyze an effective theory of the two-dimensional N = 2 supergravity, i.e., N = 2 superLiouville theory. We calculate the anomalies associated with the BRST supercurrent and the ghost number supercurrent. From those expressions of anomalies, we construct covariant BRST and ghost number supercurrents in the effective theory.We then show that the (super-)coordinate BRST current algebra forms a superfield extension of the topological conformal alg… Show more

“…As was noticed in ref. [28] for both critical and non-critical N = 2 fermionic string theories, the vanishing of the ghost-number anomaly associated with the total divergence term in the full BRST anomaly is crucial for the apparently topological properties of these theories. There are also many reasons to believe that the two-dimensional N = 2 supergravity itself is a topological quantum field theory [21,28].…”

“…Gauge superstring theories have been studied in different points of view [1,2]. They are obtained by introducing the worldsheet abelian gauge fields in superstring action [3][4][5]. The action of the gauged superstring allows us to build two worldsheet fields from elements of the gauge field.…”
