title = "Loop corrections to conformal invariance for type-I superstrings",
abstract = "BRST anomalies arising from modular integrations can be cancelled between different genus world-sheets at the price of moving the world-sheet σ-model away from its conformal fixed point. We have fully implemented this procedure for the lowest-loop corrections to the type-I superstring. The associated conformal invariance violations are responsible for important corrections to the background field equations including both the coupling of the gauge field to gravity and the anomaly-cancelling interactions of the antisymmetric tensor field.",

note = "Funding Information: All anomalies of interest to us derive from the disappearance of zero-mass bosons into the vacuum. For the closed sector of the type-I superstring these bosons are the metric perturbation h~,,,=g~-5~, the ghost dilaton • [ 8 ], and the antisymmetric tensor field strength H~p. In the presence of condensates of these fields, the world-sheet a-model is summarized by an operator Supported in part by DOE Grant DE-AC02-76ER-03072. z On leave from Rutgers University, New Brunswick, NJ 08903, USA. 3 Supported in part by NSF Grant PHY84-15534. 4 Supported in part by NSF Grant PHY80-19754. 5 Present address: University of Florida, Gainesville, FL 32611, USA. 6 Supported in part by DOE Grant DE-FG05-86ER-40272.",
