The Scalar Field Of 5D Gravity And The Higgs Field Of 4D Particle Physics: A Possible Connection

Abstract

The main results are reviewed of relating the scalar field of noncompactified Kaluza-Klein gravity to the Higgs field of particle physics. The embedding of 4D spacetime in a 5D manifold can result in a variable cosmological 'constant' and particle masses tiny compared to the Planck value.
