The density of relic neutrinos is expected to be enhanced due to clustering in our local neighbourhood at Earth.We introduce a novel analytical technique to click here calculate the neutrino overdensity, based on kinetic field theory.Kinetic field theory is a particle-based theory for cosmic structure formation and in this work we apply it for the first time to massive neutrinos.The gravitational interaction is expanded in a perturbation series and bovi-shield gold fp 5 l5 we take into account the first-order contribution to the local density of relic neutrinos.
For neutrino masses that are consistent with cosmological neutrino mass bounds, our results are in excellent agreement with state-of-the-art calculations.
