abstract

In this work one shows that a generalized non-minimal coupling between geometry and matter is compatible with Starobinsky inflation and leads to a successful process of preheating, a reheating scenario based on the production of massive particles via parametric resonance. The model naturally extends the usual preheating mechanism, which resorts to an {\it ad-hoc} scalar curvature-dependent mass term for a scalar field $\chi$, and also encompasses a previously studied preheating channel based upon a non-standard kinetic term.

Fitting a one-parameter modified gravity model to Pantheon+, DES, and BAO data gives mixed evidence: the n=6 version is preferred by information criteria in most combinations, but n=4 and n=10 are often disfavored, an...
