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

摘要

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