Higgs Scalar-Tensor Theory for Gravity and the Flat Rotation Curves of Spiral Galaxies

TL;DR

This paper proposes a Higgs scalar-tensor gravity theory that explains flat galaxy rotation curves by modeling galaxies as polytropic gas spheres with a massive core, aligning theory with observations.

Contribution

It introduces a novel scalar-tensor gravity model using the Higgs field to account for galaxy rotation curves, integrating particle physics with astrophysical phenomena.

Findings

Reproduces observed flat rotation curves of galaxies.

Models galaxies as polytropic gas spheres with a massive core.

Provides a theoretical framework linking Higgs field to galactic dynamics.

Abstract

The scalar-tensor theory of gravity with the Higgs field as scalar field is presented. For central symmetry it reproduces the empirically measured flat rotation curves of galaxies. We approximate the galaxy by a polytropic gas sphere with the polytropic index $\gamma=2$ and a massive core.
