Mikheyev (A. Yu. Mikheyev)

A. Yu. Mikheyev is a physicist known for his work on neutrino oscillations— the phenomenon where neutrinos, tiny subatomic particles, change types as they travel. Along with scientists like Lincoln Wolfenstein and colleagues, Mikheyev contributed to the development of the "MSW effect," which explains how neutrinos interact with matter such as the Sun's interior, altering their behavior. This work has helped scientists better understand neutrino properties and solved long-standing puzzles about solar neutrino observations, advancing our knowledge of fundamental particle physics and the universe.
