Phys. Rev. D 34, 2292–2297 (1986)Anomalous but consistent gravity in two dimensionsReceived 27 June 1986; published in the issue dated 15 October 1986 Two-dimensional gravity coupled to chiral fermions possesses a Lorentz anomaly, but it can be made consistent by allowing the gauge degree of freedom to be physical at the quantum level. The theory has massless excitations or a ghost particle depending on the sign of a counterterm. The possibility of adding the Wess-Zumino term in order to cancel the anomaly is also discussed. © 1986 The American Physical Society URL:
