Is there any physics beyond q 13 ?

We have measured a cosmological constant that is different from zero

• Low Homestake rate ? • Absence of the upturn of the spectrum ?

Turn down at low energies ?

• Low Homestake rate ? • Absence of the upturn of the spectrum ? Next Kam. LAND data release: still some shift in Dm 2 is not excluded….

There is a rich non-q 13 program which might help make the q 13 program happen.
