A COSMOLOGICAL LOWER LIMIT FOR QUARK COMPOSITENESS ENERGY SCALE
Keyword(s):
Baryon number density inhomogeneity in the very early universe, due to an assumed first order preon-to-quark phase transition, at or around the electroweak symmetry breaking energy is discussed. Conformity with primordial nucleosynthesis suggests that quark compositeness energy scale must be higher than 500 GeV.
