Reheating study of sombrero-type symmetry-breaking potentials
Abstract
Abstract We study reheating in sombrero-type symmetry-breaking potentials, emphasizing the role of the post-inflationary equation-of-state parameter( ω̅ re ) in shaping observable predictions. By exploring the allowed range of ω̅ re , we derive reheating temperature, e-fold counts, and inflationary observables, showing that the double well potential satisfies Planck+BK18+BAO constraints on n s and r. The analysis underscores reheating as a critical link between theoretical potentials and CMB data. In addition, the holographic sombrero realization is examined as a benchmark, with our results mapping its phenomenological boundaries. This work illustrates how reheating studies sharpen constraints and guide refinements of unified inflationary scenarios.
