Future Precision Neutrino Oscillation Experiments and Theoretical Implications
Future neutrino oscillation experiments will lead to precision measurements
of neutrino mass splittings and mixings. The flavour structure of the lepton
sector will therefore at some point become better known than that of the quark
sector. This article discusses the potential of future oscillation experiments
on the basis of detailed simulations with an emphasis on experiments which can
be done in about ten years. In addition, some theoretical implications for
neutrino mass models will be briefly discussed.Comment: Talk given at Nobel Symposium 2004: Neutrino Physics, Haga Slott,

Underground operation of the ICARUS T600 LAr-TPC: first results
Open questions are still present in fundamental Physics and Cosmology, like
the nature of Dark Matter, the matter-antimatter asymmetry and the validity of
the particle interaction Standard Model. Addressing these questions requires a
new generation of massive particle detectors exploring the subatomic and
astrophysical worlds. ICARUS T600 is the first large mass (760 ton) example of
a novel detector generation able to combine the imaging capabilities of the old
famous "bubble chamber" with an excellent energy measurement in huge electronic
detectors. ICARUS T600 now operates at the Gran Sasso underground laboratory,
studying cosmic rays, neutrino oscillation and proton decay. Physical
potentialities of this novel telescope are presented through few examples of
neutrino interactions reconstructed with unprecedented details. Detector design
and early operation are also reported.Comment: 14 pages, 8 figures, 2 tables. Submitted to Jins
Effect of Collective Flavor Oscillations on the Diffuse Supernova Neutrino Background
Collective flavor oscillations driven by neutrino-neutrino self interaction
inside core-collapse supernovae have now been shown to bring drastic changes in
the resultant neutrino fluxes. This would in turn significantly affect the
diffuse supernova neutrino background (DSNB), created by all core-collapse
supernovae that have exploded in the past. In view of these collective effects,
we re-analyze the potential of detecting the DSNB in currently running and
planned large-scale detectors meant for detecting both electron neutrinos and
antineutrinos. The next generation detectors should be able to observe DSNB
fluxes. Under certain conducive conditions, one could learn about neutrino
parameters. For instance, it might be possible to determine the neutrino mass
hierarchy, even if theta_{13} is almost zero.Comment: Ver3 (24 pages, 4 figures and 4 tables): Reference added. Figure 1
