Effective cosmological constant from TeV-scale physics

TL;DR

This paper proposes a modification to q-theory equations that explains the observed cosmological constant as a remnant of TeV-scale physics, suggesting new particles beyond the standard model at energies of 3 to 9 TeV.

Contribution

It introduces a simple modification to q-theory dynamics that yields the correct order of magnitude for the cosmological constant, linking it to TeV-scale physics.

Findings

Remnant vacuum energy density matches observed Lambda.

Estimated energy scale E_{ew} is between 3 and 9 TeV.

Suggests existence of new TeV-scale particles beyond the standard model.

Abstract

It has been suggested previously that the observed cosmological constant Lambda corresponds to the remnant vacuum energy density of dynamical processes taking place at a cosmic age set by the mass scale M \sim E_{ew} of ultramassive particles with electroweak interactions. Here, a simple modification of the nondissipative dynamic equations of q-theory is presented, which produces a remnant vacuum energy density (effective cosmological constant) of the correct order of magnitude. Combined with the observed value of Lambda, a first estimate of the required value of the energy scale E_{ew} ranges from 3 to 9 TeV, depending on the number of species of ultramassive particles and assuming a dissipative coupling constant of order unity. If correct, this estimate implies the existence of new TeV-scale physics beyond the standard model.
