Lecture
Nucleosynthesis and Neutrino Decoupling
Description
This lecture covers the evolution of entropy in an expanding Universe, the estimation of temperature changes, the conservation of entropy with high accuracy, and the impact of neutrino decoupling temperature on massless neutrinos. It also discusses the creation of light elements, the abundance of helium, and the constraints on particle masses. The lecture concludes with a detailed explanation of the Big Bang Nucleosynthesis (BBN) and the physical interpretation of key parameters.
