Shift-symmetries at higher order

The fate of shift-symmetries in effective string models is considered beyond tree-level. such symmetries have been proposed in the past as a way to maintain a hierarchically small higgs mass and also play a role in schemes of cosmological relaxation. it is argued that on general grounds one expects shift-symmetries to be restored in the limit of certain asymmetric compactifications, to all orders in perturbation theory. this behaviour is verified by explicit computation of the kähler potential to one-loop order.
