Linear perturbation theory and structure formation in a Brans-Dicke theory of gravity without dark matter
Lorenzo Gervani, Antonaldo Diaferio, Francesco Pace +1
We investigate the formation of the large-scale cosmic structure in a scalar-tensor theory of gravity belonging to the class of the Brans--Dicke theories. The universe contains bar…

Gravity with higher-curvature terms and second-order field equations: meets Gauss-Bonnet
Fabrizio Corelli, Paolo Pani, Andrea P. Sanna
General Relativity is expected to break down in the high-curvature regime. Beyond an effective field theory treatment with higher-order operators, it is important to identify consi…
