Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

The exploration of neutrino mass has long been recognized as
a powerful probe for new physics beyond the well established Standard
Model of the Electro-Weak Interaction. Experiments searching for Neutrino
Oscillations have, quite convincingly, demonstrated the existence of this
effect, and therefore of finite neutrino mass, using a variety of
different techniques. The natural question arises: what's next? While
oscillation experiments are well suited to precisely map the neutrino
mixing matrix they are, on the other hand, only sensitive to the
differences of the squared neutrino masses, and therefore fundamentally
unsuited to determine the absolute neutrino mass. The exploration of the
neutrino-less double decays and kinematic neutrino mass tests are
currently our most sensitive tools to answer this question. In addition
double beta decay is closely related to the, yet unknown, behavior of
neutrinos under CP-conjugation and the conservation of the Lepton number.
__ In my talk I will put the goals of a new generation of double beta
decay searches into the perspective of the oscillation experiments.
A subjective selection of these projects will be discussed, along
with the experimental challenges and anticipated results.
Refreshments will be served at 10:10 a.m.
