Title: Neutrino Pre-Town Meeting This is a town meeting: make your voice heard!


1
Neutrino Pre-Town MeetingThis is a town meeting
make your voice heard!
2
What we hope to do at the breakout sessions - The
Agenda
  • Discover and hear about the various ideas for
    current and future research
  • Collect these ideas and try to uncover common
    themes
  • Begin discussions about the given section of a
    white paper
  • All slides are open to modification and input As
    the discussion proceeds, well try to collect our
    comments here.

Neutrino Physics is
Nuclear Physics
Particle Physics
Astrophysics
Cosmology
And probably others as well. But it is the NP
Long range plan we are trying to influence.
4
Key Goals
  • Want to deliver an effective message to the Town
    Meeting in January
  • We need to
  • Identify a coherent set of physics goals
  • Articulate why the research is nuclear physics
    and should be supported by NP
  • Indicate why the next 5 years are critical to
    this research
  • Identify critical needs

Neutrino Pre-Town MeetingThis is a town meeting

  • Neutrino Mass, Charge Conjugation, Lepton Flavor
    Violation Working Group
  • Conveners Steve Elliott/Guido Drexlin

6
Our working group includes, but is not
necessarily limited to
  • How do we
  • determine the masses of the neutrinos?
  • their charge-conjugation properties?
  • determine if Lepton number conservation is
    violated?

7
Beta Decay
  • Why Nuclear Physics?
  • Nuclear decay process
  • Fundamental particle participating in nuclear
    transition
  • Traditional nuclear-physics experimental
    techniques
  • Why now?
  • Some experiments are being built
  • Other experiments need RD support

8
Beta Decay representative list
  • Tritium - KATRIN, NEXTEX (Abstract)
  • 187Re - MARE
  • Theory weak interaction descriptions, non-SM
    extensions

9
Double-Beta Decay
  • Why Nuclear Physics?
  • Nuclear decay process
  • Fundamental particle participating in nuclear
    transition - the characteristics of that particle
    are critical to the nuclear process
  • Backgrounds result from nuclear processes, thus
    experimenters require NP understanding
  • Traditional nuclear-physics experimental
    techniques
  • Important nuclear theory component
  • Why now?
  • Some experiments are being built
  • Other experiments need RD support
  • Critical needs
  • Underground laboratory

  • 116Cd (COBRA, )
  • 130Te (CUORE, COBRA)
  • 136Xe (EXO)
  • 150Nd (SNO)
  • Theory nuclear matrix elements, RH currents, ?
    phenomenology

Dark Matter
  • Why Nuclear Physics?
  • Traditional nuclear-physics experimental
    techniques
  • Backgrounds result from nuclear processes, thus
    experimenters require NP experience
  • Important nuclear theory component
  • Why now?
  • Some experiments are being built
  • Other experiments need RD support
  • Critical Needs
  • Underground laboratory
