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