Title: Nuclear Science


1
Nuclear Science the New Standard Model
Neutrinos Fundamental Symmetries in the Next
Decade
Fifty years of PV in nuclear physics
Solar ns the neutrino revolution
Michael Ramsey-Musolf, INPC 2007
2
Fundamental Symmetries Cosmic History

Fundamental Symmetries Cosmic History
4
Fundamental Symmetries Cosmic History
Puzzles the Standard Model cant solve
  • Origin of matter
  • Unification gravity
  • Weak scale stability
  • Neutrinos

What are the symmetries (forces) of the early
universe beyond those of the SM?
5
Opportunity Unique role for low energy studies
in the LHC era
(and beyond!)
6
Primary Scientific Questions
7
Specific Opportunities
  • Major Discovery Potential
  • 0nbb-decay EDM
  • Precision measurements
  • Neutrino mixing hierarchy
  • Weak decays, PVES, gm-2
  • Electroweak probes of QCD
  • PVES, Hadronic PV, nN scatt
