Neutrino in Cosmology - Lecture 1

Explore the role of neutrinos in cosmology through this comprehensive lecture by Yvonne Wong, part of the "Understanding the Universe Through Neutrinos" program at the International Centre for Theoretical Sciences. Delve into the fascinating world of these elusive particles and their impact on our understanding of the universe. Learn about neutrino oscillations, their tiny but non-zero masses, and how they challenge the Standard Model of particle physics. Discover the key questions that remain open in neutrino physics, including their nature as Majorana particles, the possibility of sterile neutrinos, mass ordering, and CP symmetry violation. Gain insights into the specialized experiments designed to study these ghostly particles and their implications for physics beyond the Standard Model. This lecture is ideal for PhD students and early postdocs working in or entering the field of neutrino physics, offering a solid foundation for future research in this vibrant area of study.
