Goldstone Bosons as Fractional Cosmic Neutrinos
Steven Weinberg
(Submitted on 8 May 2013)
It is suggested that Goldstone bosons may be masquerading as fractional cosmic neutrinos, contributing about 0.39 to what is reported as the effective number of neutrino types in the era before recombination. The broken symmetry associated with these Goldstone bosons is further speculated to be the conservation of the particles of dark matter.
