Figuring out which type of neutrino is heaviest, or solving the puzzle of neutrino mass hierarchy, would be a huge leap in our understanding of both neutrinos and the physics that govern our universe. The NoVA experiment or DUNE could help physicists do just that.
From China Science News, Yunnan.cn (China), April 1, 2021: The Muon g-2 experiment conducted at the Fermilab will soon announce the results after 20 years of waiting.
Theoretical particle physics employs very difficult mathematics, so difficult that it is impossible to solve the equations. So scientists employ a mathematical technique called perturbation theory, which makes it possible to solve very difficult problems with very good precision.
