Cosmological observations, such as Big Bang Nucleosynthesis (BBN) and the Cosmic Microwave Background (CMB), provide vital insights into the early Universe, allowing us to trace its evolution to times as short as t∼0.01 s and to test extensions of the Standard Model. Accurately modeling the non-trivial dynamics of neutrinos in the decoupling era typically requires solving a system of Boltzmann equations numerically, a method that comes with inherent limitations, particularly in terms of computational efficiency for high neutrino energies. In this talk, a novel approach based on the Direct Simulation Monte Carlo (DSMC) method is presented, which offers significant advantages over traditional techniques, particularly in scenarios involving high-energy neutrino injections.
