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 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. https://www.roneverhart.com/HP-Pavilion-15-eg2373cl-15-6-FHD-Touch-Laptop-Intel-Core-i7-1255U-3-50-GHz-GeForce-MX550-16GB-DDR4-512GB-SSD-Windows--p8309/
