Unitarization of $R + I^\pm R^{2}$ gravity

IÃ±igo AsiÃ¡in, Antonio Dobado, DomÃ¨nec Espriu

We make use of the improved K-matrix algorithm to obtain unitarized amplitudes in $R + I^\pm R^{2}$ gravity (the so-called Starobisnsky model, of cosmological relevance). The procedure is…

Propagating degrees of freedom on maximally-symmetric backgrounds in $f (R)$ theories of gravity

AdriÃ¡n Casado-TurriÃ³n, Ãlvaro de la Cruz-Dombriz, Antonio Dobado

In the context of $f (R)$ gravity, as well as other extended theories of gravity, the correct counting of globally well-defined dynamical modes has recently drawn a vivid interest.…
