Ev. Sedelnikov et My. Khlopov, COSMIC-RAYS AS AN ADDITIONAL SOURCE OF INFORMATION ABOUT NONEQUILIBRIUM PROCESSES IN THE UNIVERSE, Physics of atomic nuclei, 59(6), 1996, pp. 1000-1004
It is shown that cosmic rays may serve as a source of information abou
t nonequilibrium processes in the universe (evaporation of primordial
black holes, annihilation of domains of antimatter, decays of metastab
le particles, etc.) over a long period of cosmological evolution begin
ning from t similar to 10(12) s until the present time. Such processes
are associated with the hypothetical physics of phenomena that occur
in the very early universe as predicted by modern unified field theori
es.
