# Asymptotic nonlocality

@article{Boos2021AsymptoticN, title={Asymptotic nonlocality}, author={Jens Boos and Christopher D. Carone}, journal={Physical Review D}, year={2021} }

We construct a theory of real scalar fields that interpolates between two different theories: a Lee–Wick theory with N propagator poles, including N − 1 Lee–Wick partners, and a nonlocal infinite-derivative theory with kinetic terms modified by an entire function of derivatives with only one propagator pole. Since the latter description arises when taking the N → ∞ limit, we refer to the theory as “asymptotically nonlocal.” Introducing an auxiliary-field formulation of the theory allows one to…
