Scalar-field Pressure in Induced Gravity with Higgs Potential and Dark Matter

TL;DR

This paper investigates a scalar-field induced gravity model with a Higgs potential, analyzing pressure effects and their implications for energy density, solar system tests, galactic dynamics, and dark matter halos.

Contribution

It introduces a detailed analysis of pressure components from scalar-field excitations in induced gravity with a Higgs potential, linking them to observable astrophysical phenomena.

Findings

Pressure effects influence galactic dark matter halos

Constraints from solar-relativistic effects are considered

Implications for energy density and dark matter distribution

Abstract

A model of induced gravity with a Higgs potential is investigated in detail in view of the pressure components related to the scalar-field excitations. The physical consequences emerging as an artifact due to the presence of these pressure terms are analysed in terms of the constraints parting from energy density, solar-relativistic effects and galactic dynamics along with the dark matter halos.
