### Nuclear Science & the New Standard Model: Neutrinos & Fundamental Symmetries in the Next Decade

The next decade presents NP with a historic opportunity to build on this legacy in developing the “new Standard Model”

The value of our contribution will be broadly recognized outside the field

Nuclear physics studies of ns & fundamental symmetries played an essential role in developing & confirming the Standard Model

Our role has been broadly recognized within and beyond NP

Solar ns & the neutrino revolution

Fifty years of PV in nuclear physics

Michael Ramsey-Musolf, NSAC March, 2007
