Primordial perturbations generated by Higgs field and R^2 operator release_iim5rpcipvdzxjcfokwbdxsvyi

Released as a article .



If the very early Universe is dominated by the non-minimally coupled Higgs field and Starobinsky's curvature-squared term together, the potential diagram would mimic the landscape of a valley, serving as a cosmological attractor. The inflationary dynamics along this valley is studied, model parameters are constrained against observational data, and the isocurvature perturbation is evaluated.
