There must have been additional symmetries in the
earlier Universe to

• Unify all matter, space, time
• Stabilize the weak scale
• Produce all the matter that exists
• Account for neutrino properties

• Give self-consistent quantum gravity

Summary

• Precision NP studies of neutrinos and fundamental
  symmetries are poised to discovery key
  ingredients of the new Standard Model during the
  next decade
• Physics reach complements and can even exceed
  that of colliders
• Substantial experimental and theoretical progress
  has set the foundation for this era of discovery
• The precision frontier is richly
  interdisciplinary nuclear, particle, hadronic,
  atomic, cosmological
