Cosmological Constraints on a Massive Neutrino
Masahiro Kawasaki, Katsuhiko Sato
TL;DR
This paper explores how cosmological observations can constrain the properties of massive neutrinos, linking particle physics with cosmology and inspiring subsequent research in the field.
Contribution
It was among the first to analyze the cosmological effects of massive neutrinos, establishing a foundation for using cosmology to study particle physics.
Findings
Constraints on neutrino mass from cosmology
Link between neutrino properties and early universe physics
Pioneered use of cosmological data in neutrino research
Abstract
The paper by Sato and Kobayashi in 1977 studied the cosmological effects of a massive neutrino and obtained constraints on its properties. This paper initiated many studies to use cosmology as a laboratory of particle physics or to use particle physics to explore the very early universe.
