TL;DR: In this article, a reevaluation applies to all reactor neutrino experiments and the compatibility of their results with the existence of a fourth nonstandard neutrinos state driving neutrini oscillations at short distances is discussed.

TL;DR: The Double Chooz experiment presents an indication of reactor electron antineutrino disappearance consistent with neutrino oscillations, and an observed-to-predicted ratio of events of 0.944±0.016 and a deficit can be interpreted as a nonzero value of the still unmeasured neutrinos mixing parameter sin(2)2θ(13).

TL;DR: In this paper, the authors report new calculations of antineutrino spectra including the latest information from nuclear databases and a detailed error budget, which is based on the so-called ab initio approach where the sum of all beta-branches of all fission products predicted by an evolution code.

TL;DR: The Double Chooz experiment has observed 8,249 candidate electron antineutrino events in 227.93 live days with 33.71 GW-ton-years (reactor power x detector mass x livetime) exposure using a 10.3 cubic meter fiducial volume detector located at 1050 m from the reactor cores of the Choock nuclear power plant in France as discussed by the authors.

TL;DR: In this article, the authors reanalyze the data and find a ratio R=0.903 +-0.01(stat), leading to sin^2 2theta13 = 0.135.
