Abstract:

A new experiment at the Chooz reactor in France is being planned to measure anti-neutrino disappearance which extends sensitivity to the neutrino oscillation parameter theta-13. The best current limit on theta-13 comes from the previous reactor neutrino experiment CHOOZ. The new experiment, a collaboration of European and US physicists, will use two 15-ton detectors to reduce most systematic errors. If fully approved in 2005, it will reach the CHOOZ sensitivity by early 2008, and sine squared of twice theta < 0.03 by 2010.
