Abstract: In this work we consider the Higgs inflation scenario, but in contrast with past works, the present analysis is done in the context of a spontaneous collapse theory for the quantum state of the inflaton… read more here.

DOI: 10.1088/1475-7516/2021/01/032
Abstract: Primordial black holes are produced in a minimal UV extension to the Higgs inflation with an included R2 term. We show that for parameters consistent with Standard Model measurements and Planck observation results lead to… read more here.

DOI: 10.1103/physrevd.102.063522
Abstract: The predictions of standard Higgs inflation in the framework of the metric formalism yield a tensor-to-scalar ratio $r \sim 10^{-3}$ which lies well within the expected accuracy of near-future experiments $ \sim 10^{-4}$. When the… read more here.

DOI: 10.1103/physrevd.98.103524
Abstract: Higgs inflation and $R^2$-inflation (Starobinsky model) are two limits of the same quantum model, hereafter called Starobinsky-Higgs. We analyse the two-loop action of the Higgs-like scalar $\phi$ in the presence of: 1) non-minimal coupling ($\xi$)… read more here.
