Local clustering of relic neutrinos with kinetic field theory

Blog Article

The density of relic neutrinos is expected to be enhanced due to kt196 torque converter clustering in our local neighbourhood at Earth.We introduce a novel analytical technique to 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 click here in a perturbation series and 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.
