Starobinsky Inflation and the Latest CMB Data: A Subtle Tension?

J. Bezerra-Sobrinho, L. G. Medeiros

We analyze the Starobinsky inflation model and the impact of curvature corrections, particularly a cubic $R^{3}$ term, to assess their behavior in light of the latest observational r…

Brans-Dicke-like field for co-varying $G$ and $c$ : observational constraints

J. Bezerra-Sobrinho, R. R. Cuzinatto, L. G. Medeiros +1

Ref. [Symmetry 15 (2023) 709] introduced a Brans-Dicke-like framework wherein the scalar field $ϕ$ is composed of both $G$ and $c$ which, for this reason, co-vary according to $c^{…
