Dirac neutrino mass from a neutrino dark matter model for the galaxy cluster Abell 1689
arXiv:1510.06958 · doi:10.1088/1742-6596/701/1/012022
Abstract
The dark matter in the galaxy cluster Abell 1689 is modelled as an isothermal sphere of neutrinos. New data on the mass density allow an accurate description of its core and halo. The model has no "missing baryon problem" and beyond Mpc the baryons have the cosmic mass abundance. Combination of cluster data with the cosmic dark matter fraction -- here supposed to stem from the neutrinos -- leads to a solution of the dark matter riddle by left and right handed neutrinos with mass 1.847 +/- 0.016 eV. The thus far observed absence of neutrinoless double beta decay points to (quasi-) Dirac neutrinos: uncharged electrons with different flavour and mass eigenbasis, as for quarks. Though the cosmic microwave background spectrum is matched up to some 10\% accuracy only, the case is not ruled out because the plasma phase of the early Universe may be turbulent.
