Stratified scalar field theories of gravitation with self-energy term
  and effective particle Lagrangian
  We construct a general stratified scalar theory of gravitation from a field
equation that accounts for the self-interaction of the field and a particle
Lagrangian, and calculate its post-Newtonian parameters. Using this general
framework, we analyze several specific scalar theories of gravitation and check
their predictions for the solar system post-Newtonian effects.
