Origin of masses in the Early Universe

TL;DR

This paper proposes a novel model where the Casimir effect explains the origin of masses and symmetry breaking in the early Universe, providing new insights into the Higgs mass and scalar field interactions.

Contribution

It introduces a Casimir-based mechanism for mass generation and conformal symmetry breaking at the Planck epoch, differing from the Standard Model approach.

Findings

Casimir energy and condensate can determine the Higgs mass without a tachyonic mass.

The Casimir mechanism predicts a different scalar self-interaction coupling constant.

The model links vacuum properties to fundamental particle masses in the early Universe.

Abstract

New model is suggested, where the Casimir mechanism is the source of masses and conformal symmetry breaking at the Planck epoch in the beginning of the Universe. The mechanism is the Casimir energy and associated condensate, which are resulted from the vacuum postulate and normal ordering of the conformal invariant Hamiltonian with respect to the quantum elementary field operators. It is shown that the Casimir top-quark condensate specifies the value of the Higgs particle mass without involving the Higgs tachyon mass, which is put equal to zero. The Casimir mechanism yields another value of the coupling constant for the self-interaction of scalar field than the standard model does.
