Key Questions of Particle Physics

  • Are there undiscovered principles of nature: new symmetries, new physical laws?
  • How can we solve the mystery of dark energy? Dark energy that permeates empty space must have a quantum explanation. Is it related to the Higgs field?
  • Are there extra dimensions of space?
  • Do all the forces become one at the most fundamental level?
  • Why are there exactly 3 families (generations, flavors) of fermions. Why do their masses differ so dramatically?
  • What is dark matter? How can we make it in the laboratory?
  • What are neutrinos telling us? What role did neutrinos play in the evolution of the universe? Their tiny nonzero masses may signal new physics.
  • How did the universe come to be? Understanding the universe’s inflationary expansion and formation of matter after the big bang requires new theories.
  • What happened to the anti-matter? The big bang should have produced equal amounts of matter and anti-matter, yet the anti-matter is gone. What happened?
  • Do all the neutrino types oscillate into the other types?
  • Are neutrinos their own anti-particles?
  • Do neutrinos interact differently with matter than with anti-matter?
