Abstract Asymptotically nonlocal field theories represent a sequence of higher-derivative theories whose limit point is a ghost-free, infinite-derivative theory. Here we extend this framework, developed previously in a theory of real scalar fields, to gauge theories. We focus primarily on asymptotically nonlocal scalar electrodynamics, first identifying equivalent gauge-invariant formulations of the Lagrangian, one with higher-derivative terms and the other with auxiliary fields instead. We… Expand

Nonlocal gauge theories
Nonlocal gauge theories, including gravitation, are considered. It is shown that to give a meaning to /gamma//sub 5/-anomalous theories it is sufficient to introduce an additional nonlocalExpand
Superrenormalizable gauge and gravitational theories

In this paper we study perturbatively an extension of the Stelle higher derivative gravity involving an infinite number of derivative terms. We know that the usual quadratic action is renormalizableExpand
Cutkosky rules and perturbative unitarity in Euclidean nonlocal quantum field theories
We prove the unitarity of the Euclidean nonlocal scalar field theory to all perturbative orders in the loop expansion. The amplitudes in the Euclidean space are calculated assuming that all theExpand
Unitarity and microscopic acausality in a nonlocal theory
We consider unitarity and causality in a higher-derivative theory of infinite order, where propagators fall off more quickly in the ultraviolet due to the presence of a transcendental entire functionExpand
Nonsingular metric for an electrically charged point-source in ghost-free infinite derivative gravity

Cutkosky rules for superstring field theory
A bstractSuperstring field theory expresses the perturbative S-matrix of superstring theory as a sum of Feynman diagrams each of which is manifestly free from ultraviolet divergences. The interactionExpand
Classical gravity with higher derivatives
Inclusion of the four-derivative terms ∫RμνRμν(−g)1/2 and ∫R2(−g)1/2 into the gravitational action gives a class of effectively multimass models of gravity. In addition to the usual masslessExpand
A new formulation of Lee-Wick quantum field theory
A bstractThe Lee-Wick models are higher-derivative theories that are claimed to be unitary thanks to a peculiar cancelation mechanism. In this paper, we provide a new formulation of the models, toExpand
