Solving the Cosmological Entropy Issue with a Higgs Dilaton

TL;DR

This paper proposes a novel cosmological model where the Higgs field acts as a dilaton, weakening gravity in the early universe to address the initial smoothness problem and offering an inflationary scenario consistent with observations.

Contribution

It introduces a Higgs-based dilaton model that modifies early universe gravity, providing an alternative to conformal cyclic cosmology and linking inflation to particle physics.

Findings

Weakens gravity at early times to solve initial condition problems.

Provides an inflationary model compatible with current observations.

Connects inflationary dynamics directly to the Higgs field.

Abstract

Current cosmological models require the universe to be in a very smooth initial state before the onset of inflation, a situation to which Penrose ascribes a vanishingly small probability, leading to his proposal of a Conformal Cyclic Cosmology. We present an alternative paradigm, in which the Higgs plays the role of dilaton and resolves this problem by weakening gravity at very early times, thus providing a form of inflation that is compatible with observations and in which the inflaton is solidly related to tested particle physics.
