    "abstract": "Various theories of spinning particles are interpreted as realizing elements\nof an underlying geometric theory. Classical particles are described by\ntrajectories on the Poincare group. Upon quantization an eleven-dimensional\nKaluza-Klein type theory is obtained which incorporates spin and isospin in a\nlocal SL(2,C) x U(1) x SU(2) theory with broken U(1)x SU(2) part.",
