Tsutomu Yanagida is a Japanese physicist who first proposed the seesaw mechanism in 1979 and developed the model of leptogenesis. The name of the seesaw mechanism was given by him in a Tokyo conference in 1981. In 1994, he predicted, together with M. Fukugita, the nonzero cosmological constant Λ = (3 ± 1 meV)4 M. Fukugita and T. Yanagida, Model for the cosmological constant, Preprint of Yukawa Institute Kypto, YITP/K-1098 (February 1994); How do we understand a small cosmological constant, in Proceedings of International Conference on Nonlinear Dynamics, Chaotic and Complex Systems, (November 1995, Tokyo) 127-131. four years prior to the observationFor information about the cosmological constant please see this page. in order to resolve the age discrepancy between the Universe and some old stars.
Tsutomu Yanagida received a PhD in physics at Hiroshima University in 1977. Short description at Academy of Sciences and Humanities in Hamburg In 1979, he proposed the seesaw mechanism, that explains the mass of by introduction heavy right-handed neutrinos. Together with M. Fukugita, he developed the model of leptogenesis that traces the baryon asymmetry back to a lepton asymmetry. Till 2019 he was professor at Kavli Institute for Physics and Mathematics of the Universe at Tokio University. Some of his students in Tokyo were Yasunori Nomura, Junji Hisano and Takeo Moroi. students at academictree.org In 2019, he was appointed professor at Shanghai Jiao Tong University. report of appointment His research includes theoretical particle physics, string theory and cosmology. Yanagida works on super symmetry, inflation and the baryon asymmetry. He is corresponding member of the Academy of Sciences and Humanities in Hamburg. Corresponding member at Academy of Sciences and Humanities in Hamburg In 2017 he visited the Higgs Centre of Theoretical Physics at Edinburgh University as guest scientist.
