U.S. Particle Physics Strategy

  • In 2014 U.S. strategic planning panel

provided recommendations covering all main topics of the U.S. particle physics

  • They are grouped around “science

drivers”

  • Use the Higgs boson as a new tool for

discovery

  • Pursue the physics associated with

neutrino mass

  • Identify the new physics of dark matter
  • Understand cosmic acceleration: dark

energy and inflation

  • Explore the unknown: new particles,

interactions, and physical principles

  • Fermilab is leading and actively involved

in the experiments devoted to all “science drivers”
