We present a search for signatures of neutrino mixing of electron anti-neutrinos with additional hypothetical sterile neutrino flavors using the Double Chooz experiment. The search is based on data from 5 years of operation of Double Chooz, including 2 years in the two-detector configuration. The analysis is based on a profile likelihood, i.e. comparing the data to the model prediction of disappearance in a data-to-data comparison of the two respective detectors. The analysis is optimized for a model of three active and one sterile neutrino. It is sensitive in the typical mass range ${5 \times 10^{-3}}\,\mathrm{eV}^2 \lesssim \varDelta m^2_{41} \lesssim {3 \times 10^{-1}}\,\mathrm{eV}^2 $ for mixing angles down to $\sin ^2 2\theta _{14} \gtrsim {0.02} $. No significant disappearance additionally to the conventional disappearance related to $\theta _{13} $ is observed and correspondingly exclusion bounds on the sterile mixing parameter $\theta _{14} $ as a function of $ \varDelta m^2_{41} $ are obtained.Read less <
