摘要:Placing constraints on the neutrino mass is an important goal in modern physics. One important
limit on the neutrino mass can be deduced from the cosmological constraint on the formation of
large scale structure as the neutrinos become nonrelativistic at late times. On the other hand we
have shown that the development of large scale structure and the limits on the neutrino mass are
also affected by the existence of the primordialmagnetic field. We havemade an analysis of limits
on the neutrino mass which includes the formation of large scale structure in the presence of the
primordial magnetic field. We find that the combined constraint from the formation of large-scale
structure and the limits on the primordial magnetic field imply an upper limit on the mass of the
neutrino of mn < 0.8 eV(Nn = 3).
