Dear Colleagues:

I would like to propose to discuss within your
groups at the Snowmass meeting this summer the 
routes of experimental observation of baryon 
instability that are alternative or complementary
to the proton decay searches. These include, at the
first place, a new reactor experiment for neutron - 
antineutron transition search, but also the possibility
to search for neutron to 3 neutrino decay in KamLAND, 
an improvement of mode independent nucleon decay limit
that is currently known as >1.6E+25 years, experimental
searches for (B-L) non-conservation, and discussion of
possible baryon instability in the models with gravity 
at TeV scale. At Snowmass I plan to discuss mostly 
the experimental aspects of such new searches and hope 
that there will be corresponding support from interested
theoreticians: Rabi Mohapatra, Georgi Dvali, and possibly
others.

Last year with the group of interested physicists we have 
sent a letter to HEPAP Chair Frad Gilman trying to argue 
that new reactor experiment for search of neutron-antineutron 
transitions is needed. Copy of this letter as well as another 
letter written to the members of NRC's Committee on the 
Physics of the Universe (CPU), and other related papers
with corresponding physics motivation can be found as PDF
