DESI DR2 Constraints on Coupled Hu--Sawicki $f(R)$ Gravity with Interacting Neutrinos: Implications for the Hubble and \(S_8\) Tensions

Muhammad Yarahmadi

We investigate the cosmological implications of viable Hu--Sawicki \(f(R)\) gravity models and their extension through an effective interaction with the neutrino sector. Motivated…
