Present best-fit ranges of the top and Higgs masses mostly lie in the narrow metastable region. Furthermore, we show that the SM potential can be fine-tuned in order to be made suitable for inflation. However, SM inflation results in a power spectrum of cosmological perturbations not consistent with observations.8 pages, 4 figuresHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
