Scalar-tensor theories of gravity, neutrino physics, and the H0 tension
(IOP Publishing, 2020)
We use Planck 2018 data to constrain the simplest models of scalar-tensor theories
characterized by a coupling to the Ricci scalar of the type F(σ)R with F(σ) = N2

Larger value for H0 by an evolving gravitational constant

Cosmological constraints on post-Newtonian parameters in effectively massless scalar-tensor theories of gravity
(2019)
We study the cosmological constraints on the variation of Newton’s constant and on post-Newtonian
parameters for simple models of the scalar-tensor theory of gravity beyond the extended Jordan-BransDicke theory. We restrict ...
