Creation of neutral fundamental particles in the Weyl-Dirac version of Wesson's IMT

Spherically symmetric entities filled with matter induced by the 5D Bulk may be built in the empty 4D space-time. The substance of the entity, the latter regarded as a fundamental particle, is characterized by the prematter equ. of state P=-rho. the particle is coverede by a Schwarzschild-like envelope and from the outside it is characterized by mass and radius. One regard these entities as neutral fundamental particles being constituents of quarks and leptons. The presented classical models are developed in the framwork of the Weyl-Dirac version of Wesson’s IMT.
