The Double Chooz Experiment presents an indication of reactor electron antineutrino disappearance consistent with neutrino oscillations. A ratio of 0.944 $\pm$ 0.016 (stat) $\pm$ 0.040 (syst) observed to predicted events was obtained in 101 days of running at the Chooz Nuclear Power Plant in France, with two 4.25 GW$_{th}$ reactors. The results were obtained from a single 10 m$^3$ fiducial volume detector located 1050 m from the two reactor cores. The reactor antineutrino flux prediction used the Bugey4 measurement as an anchor point. The deficit can be interpreted as an indication of a non-zero value of the still unmeasured neutrino mixing parameter \sang. Analyzing both the rate of the prompt positrons and their energy spectrum we find \sang = 0.086 $\pm$ 0.041 (stat) $\pm$ 0.030 (syst), or, at 90% CL, 0.015 $<$ \sang $\ <$ 0.16.

- Global fit to three neutrino mixing: critical look at present precision (2012, methodology): “Since the advent of data on νµ → νe searches from T2K and MINOS on the one side, and θ13 reactor experiments Double Chooz, Daya Bay, and Reno on the other side, the long anticipated complementarity of beam and reactor experiments [70, 71] is now a reality.”
- Invited review: Physics potential of the ICAL detector at the India-based Neutrino Observatory (INO) (2015, background): “A nonzero value for this angle has been discovered rather recently [35, 36, 37, 61, 62], with a moderately large best-fit value of sin(2) θ13 = 0.”
- Flavor structures of charged fermions and massive neutrinos (2019, methodology): “This smallest neutrino mixing angle can be most accurately measured in a short-baseline reactor antineutrino oscillation experiment, such as the Daya Bay [72], RENO [390] and Double Chooz [391] experiments.”
- New results on νμ → ντ appearance with the OPERA experiment in the CNGS beam (2013, background): “The first evidence of the disappearance of ν̄e has come from reactor experiments at short baselines and θ13 has been measured (Daya Bay [28], Double Chooz [29], RENO [30]).”
