Shift-symmetries at higher order.

Abel, Steven and Stewart, Richard (2016) 'Shift-symmetries at higher order.', Journal of high energy physics., 2016 (2). p. 182.


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.
