Vacuum energy and dynamical symmetry breaking in curved spacetime

TL;DR

This paper explores how vacuum energy in curved spacetime relates to dynamical electroweak symmetry breaking, proposing that the observed energy scale can be explained through composite Higgs models and potentially tested at the LHC.

Contribution

It introduces a framework connecting vacuum energy to dynamical symmetry breaking in curved spacetime, suggesting all particle masses are dynamically generated and Higgs is composite.

Findings

Vacuum energy linked to electroweak symmetry breaking.

The meV scale can be explained via electroweak physics.

Higgs boson may be a composite particle.

Abstract

We argue that calculating vacuum energy requires quantum field theory whose axioms are adapted to curved spacetime. In this context, we suggest that non-zero vacuum energy is connected to dynamical breaking of electroweak symmetry. The observed meV scale can be understood in terms of electroweak physics via a naive estimate. The scenario requires all particle masses to have a dynamical origin. Any Higgs particle has to be a composite, and the origin of vacuum energy might be probed at the LHC.
