Neutrino signals from ultracompact minihalos and constraints on the primordial curvature perturbation

Compared with that of standard dark matter halos, the density profile of the recently proposed new kind of dark matter structure named ultracompact minihalos (UCMHs) is steeper and its formation time is earlier. If the dark matter is composed of weakly interactive massive particles, the potential si...
