Research Plan
=============

If selected for the KamLAND position, my primary objective is to
contribute to efforts that will enable the collaboration to report
reliable physics results in a timely fashion.  In particular, I would
like to be involved in the calibration of the detector.  Another set
of tasks I have particular interest in are data and software quality
monitoring.  These are tasks that are often under-emphasized in a
high-profile experiment like KamLAND.  Early detection of corrupt
data, corrupt database entries, and software bugs is crucial for the
timely dissemination of physics results.  Such problems, if found in a
later stage, often lead complete loss of data and/or invasive,
time-consuming re-working of the analysis infrastructure.

I would obviously involve myself in the first main physics goal of
KamLAND: the search for a positive signal of neutrino oscillations in
the LMA region.  However, I would also like to lead an analysis effort
that might be called "exotic and rare physics" search.  Examples of
such search are nucleon decay and supernovae relic neutrino detection.
But I would extend the search to be more general.  For instance, I
would study the background sample and attempt to systematically
account for the shape of the vertex and energy distribution, for
example.  Another effort I would like to lead might be termed "the
search for physics that can be done with KamLAND, but nobody has
seriously thought of".  Examples might be:

(1) Very-high-energy neutrinos produce mostly multi-pion events.  What
    do multi-pion events look like in KamLAND?  Can we reliably
    characterize them?  If so, can we set a limit on the flux of
    neutrinos above some threshold energy?  Is this measurement
    interesting?

(2) Cosmic ray muons are spin-polarized, and the spin direction does
    not change as it stops in the detector.  Thus a Michel electron
    from a decaying stopping muon tends to decay opposite the muon
    momentum.  This sort of measurement was carried out in
    Kamiokande-II.  Is it possible to do this in KamLAND?  Is it worth
    it?

Finally, one of Hawaii group's main contribution to SK is the SKAT
water attenuation measuring device.  I am one of SK's foremost water
attenuation measurement expert.  If I can in any way contribute to the
SKAT project, I would be very much interested.
