Search for θ13 with Reactor Experiments

The actual best limits on the missing mixing angle θ13 are coming from the reactor experiment at Chooz, France. In this paper the prospectives of future reactor experiments in this field are shown. The main idea is to use two detectors at the same time, with a close one which is monitoring the reactor neutrino flux and spectrum. Hence, most of the systematic errors cancel and the sensitivity on θ13 may be enhanced significantly.
