Query: The Status of Double Chooz Experiment as a proceeding of PIC 2013
  conference   Double Chooz is a long baseline neutrino oscillation experiment at Chooz,
France. The purpose of this experiment is to measure the non-zero neutrino
oscillation parameter theta13, a parameter for changing electron neutrinos into
other neutrinos. This experiment uses reactors of the Chooz Nuclear Power Plant
as a neutrino source. Double Chooz has published 2 result papers showing the
measurement of the mixing angle, and 3rd publication is processing.
