(2) Models predicting a maximum temperature for hadronic matter are disfavored by recent experimental results indicating the presence of pointlike weakly-interacting constituents within hadrons at short distances.
(3) This result comes from the requirement that the neutrinos should not so alter the expansion rate of the early universe as to affect the amount of 
produced [8].
(4) If, however, stable 
can come from the weak decays of hadrons, then their abundances should be comparable to those of their parent hadrons had those hadrons been stable.
