New Constraints on "Cool" Dark Matter
Manuel Drees, David Wright
It has been suggested that a sterile neutrino ν_s which mixes with standard neutrinos can form nonthermal ``cool'' Dark Matter if its mass and mixing angle fall in the ranges 0.1 k…

Comment on "A New Dark Matter Candidate: Non-thermal Sterile Neutrinos"
Manuel Drees
I point out that the sterile neutrinos suggested as candidates of "cool" Dark Matter will decay through their mixing with light neutrinos. This leads to an upper bound of about 200…
