Higher-loop norm of the no-boundary state
Abstract
The leading contribution to the de Sitter no-boundary state comes from geometries with spherical spatial slices, including the Hartle-Hawking geometry and fluctuations around it. Recent work showed that this leading contribution has vanishing norm at one loop. Here we show that the norm in fact vanishes to all orders in perturbation theory.
