Long range neutrino forces in the cosmic relic neutrino background - art. no. 057304

Neutrinos mediate long range forces among macroscopic bodies in a vacuum. W hen the bodies are placed in the neutrino cosmic background, these forces a re modified. Indeed, at distances long compared to the scale T-1, the relic neutrinos completely screen off the two-neutrino exchange force, whereas f or small distances the interaction remains unaffected.
