PARTICLE MASSES IN THE EARLY UNIVERSE - MATTER AND ENTROPY PRODUCTIONS

This article deals with the particle and entropy productions in the ea rly universe, which is regarded as a thermodynamically open system in the sense of Prigogine, by incorporating the epoch dependence of eleme ntary particle masses. The epoch dependence of particle masses for som e of the Robertson-Walker (RW) universes appears as a consequence of p revious considerations of the hadronic matter extension in the inner s pace-time regarded as anisotropic and Finslerian in character. The nat ure of the evolution of the early universe has been discussed in the f ramework of the modified thermodynamic energy conservation law and the new mass formula apart from the other Einstein equation. The trivial solution of these equations is the usual inflationary stage of the ear ly universe, whereas the matter-dominated RW universe appears as the n ontrivial solution. It is shown that at the ''transition epoch'' t = 1 0(-23) sec the creation phenomenon stops and the usual cosmology of th e radiation era follows with Pascal's equation of state. This model ca n also account for the observed specific entropy per baryon of the pre sent universe and the generation of the large value of K-1, where K = Gm(p)2/hBARc, m(p) being the mass of the proton.
