#NewPaper By our theorists Antonio Racioppi and Christian Dioguardi in collaboration with Rafid H. Dejrah from Ankara University and Nilay Bostan from Marmara University about alternatives for #Gravity [1/3] arxiv.org/abs/2511.20557
Natural inflation in Palatini $F(R)$
$F(R)$ Palatini gravity provides a robust framework for constructing viable inflationary potentials. In this study, we examine natural inflation and show that its consistency with observational data c...

Has ACT measured radiative corrections to the tree-level Higgs-like inflation?
Starobinsky inflation and non-minimally coupled Higgs inflation have been among the most favored models of the early universe, as their predictions for the scalar spectral index $n_s$ and tensor-to-sc...

Fractional attractors in light of the latest ACT observations
In light of the latest results from ACT observations we review a class of potentials labeled as fractional attractors, that can originate from Palatini gravity. We show that, for certain choices of th...

Quintessential Inflation in Palatini $F(R,X)$ gravity
Palatini $F(R,X)$ gravity, with X the inflaton kinetic term, proved to be a powerful framework for generating asymptotically flat inflaton potentials. Here we show that a quadratic Palatini $F(R,X)$ r...

Natural inflation in Palatini $F(R,X)$
In the context of Palatini gravity, $F(R,X)$ models, with X the inflaton kinetic term, are characterized by the appealing property of generating asymptotically flat inflaton potentials. In this paper,...

Symmetry-breaking inflation in non-minimal metric-affine gravity
We study symmetry-breaking inflation within the framework of metric-affine gravity. By introducing a non-minimal coupling, $β(ϕ)\tilde{\cal R}$, between the Holst invariant and the inflaton, both smal...
