Abstract

We study the formation of a superfluid condensate of neutrinos inside a neutrino cluster. The attractive interaction between neutrinos is mediated by a scalar boson which is lighter than a neutrino. We consider the appearance of neutrino bound states consisting of particles with oppositely directed spins. The gap equation for such a system is derived. We find that the relativistic cosmic neutrino background can form the superfluid condensate inside a neutrino cluster having realistic characteristics.
