Neutrino CP Violation Deep Underground Bill Marciano, Brookhaven National Lab

During the last decade, tremendous advances have been made in neutrino physics.  We now know that neutrinos have mass and oscillate between species. Future steps will be to measure CP violation in neutrino oscillations, detect matter effects, determine the masses and mixing precisely and search for more exotic phenomenon perhaps due to sterile neutrinos, extra dimensions, dark energy etc.  A program to do all of the above while at the same time search for proton decay, magnetic monopoles, neutron-antineutron oscillations, relic supernova neutrinos etc. will be possible at the deep underground lab being planned for the Homestake mine in South Dakota.  It requires a very large water cerenkov detector (500kton) and an intense neutrino beam originating from Fermilab.  The physics case for this grand but doable plan will be presented.
