Quantum-corrected $$\phi ^{4}$$ ϕ 4 inflation in light of ACT observations
Abstract Recent measurements from the Atacama Cosmology Telescope (ACT), combined with Planck and DESI data, suggest a scalar spectral index $$n_s$$ n s higher than the Planck 2018 baseline, thereby placing conventional attractor-type inflationary models such as Starobinsky $$R^2$$ R 2 and Higgs inf...
