Scattering amplitudes in Quadratic Graivty in a general formalism
Osvaldo P. Santillán
In \cite{salvio}, inspired by the works \cite{pauli}-\cite{donogue}, a prescription for calculating the correlation functions in Quadratic Gravity \cite{stelle1}-\cite{stelle2} was…

Peculiarities for scalar fields in GR domain walls
Andres Felipe Tovar, Osvaldo Santillán
In the present letter, the solutions of the Klein Gordon equation in the space time of an infinite domain wall is studied. It is shown that the horizon is an special region, where…

Field response in the near-horizon limit of near-extremal 5-dimensional black holes
Gaston Giribet, Juan Laurnagaray, Bryan Malpartida +2
We study the scalar probe in the near-horizon region of near-extremal five-dimensional black holes and the problem of reattaching the asymptotic region. We consider the example of…
