Can we change c in four-dimensional CFTs by exactly marginal deformations?
Abstract There is no known obstructions, but we have not been aware of any concrete examples, either. The Wess-Zumino consistency condition for the conformal anomaly says that a cannot change but does not say anything about c. In supersymmetric models, both a and c are determined from the triangle t...
