Expected Signals in Relic Neutrino Detectors

Abstract

Here we estimate the magnitude of the signals expected for realistic cosmic neutrino backgrounds in detectors attempting to measure the mechanical forces exerted on macroscopic targets by the elastic scattering of relic neutrinos. We study effects proportional to the weak coupling constant $G_F$ and to $G_F^2$ for Dirac and Majorana neutrinos, either relativistic or non-relativistic, both gravitationally bound or not.

Comments: Included the case of non-clustered non-relativistic (NC-NR) neutrinos explicitly in G_F section
