Experimental limits on the free parameters of higher-derivative gravity
Breno L. Giacchini
Fourth-derivative gravity has two free parameters, and , which couple the curvature-squared terms and . Relativistic effects and short-range laboratory exper…
Gravitational "seesaw" and light bending in higher-derivative gravity
Antonio Accioly, Breno L. Giacchini, Ilya L. Shapiro
Local gravitational theories with more than four derivatives have remarkable quantum properties, e.g., they are super-renormalizable and may be unitary in the Lee-Wick sense. There…
Low-energy effects in a higher-derivative gravity model with real and complex massive poles
Antonio Accioly, Breno L. Giacchini, Ilya L. Shapiro
The most simple superrenormalizable model of quantum gravity is based on the general local covariant six-derivative action. In addition to graviton such a theory has massive scalar…
On the cancellation of Newtonian singularities in higher-derivative gravity
Breno L. Giacchini
Recently there has been a growing interest in quantum gravity theories with more than four derivatives, including both their quantum and classical aspects. In this work we extend t…
On the gravitational seesaw in higher-derivative gravity
Antonio Accioly, Breno L. Giacchini, Ilya L. Shapiro
Local gravitational theories with more than four derivatives are superrenormalizable, and also may be unitary in the Lee-Wick sense. Thus, it is relevant to study the low-energy pr…
