Elementary Particles as Micro - Universes : A Geometric Approach to “ Strong Gravity ”

We present here an overview of our unified, bi-scale theory of gravitational and strong interactions [which is mathematically analogous to the last version of N. Rosen’s bi-metric theory, and yields physical results similar to those of strong gravity]. This theory, developed during the last 20 years, is purely geometrical in nature, adopting the methods of General Relativity for the description of hadron structure and strong interactions. In particular, hadrons are associated with “strong black holes”, from the external point of view, and with “micro-universes”, from the internal point of view. Results presented here include derivations of (i) confinement and (ii) asymptotic freedom for hadron constituents; (iii) Yukawa behaviour for the strong potential at the static limit; (iv) the strong coupling “constant”, and (v) meson mass spectra.
