Higher-order theories from the minimal length
(2016-06-10)
We show that the introduction of a minimal length in the context of noncommutative space-time gives rise (after some considerations) to higher-order theories. We then explicitly demonstrate how these higher-derivative ...
Second order gauge theory
(Elsevier B.V., 2007-05-01)
A gauge theory of second order in the derivatives of the auxiliary field is constructed following Utiyama's program. A novel field strength G = partial derivative F + fAF arises besides the one of the first order treatment, ...

Second order higher-derivative corrections in Double Field Theory
(Springer, 2017-06)
HSZ Double Field Theory is a higher-derivative theory of gravity with exact and manifest T-duality symmetry. The first order corrections in the massless sector were shown to be governed solely by Chern-Simons deformations ...
Podolsky's electromagnetic theory on the null-plane
(2009-12-01)
We have analyzed the null-plane canonical structure of Podolsky's electromagnetic theory. As a theory that contains higher order derivatives in the Lagrangian function, it was necessary to redefine the canonical momenta ...

Renormalization of Generalized Quantum Electrodynamics
(2015-01-01)
In the present work we shall study the renormalizability of Generalized Quantum Electrodynamics (GQED4). The on-shell renormalization scheme is reviewed and applied to the theory and we calculate the explicit expressions ...
Hamilton-Jacobi approach for first order actions and theories with higher derivatives
(Academic Press Inc. Elsevier B.V., 2008-03-01)
In this work, we analyze systems described by Lagrangians with higher order derivatives in the context of the Hamilton-Jacobi formalism for first order actions. Two different approaches are studied here: the first one is ...
