abstract="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 x 10(-3) eV(2) less than or similar to Delta m(41)(2) less than or similar to 3 x 10(-1) eV(2) for mixing angles downto sin(2) 2 theta(14) greater than or similar to 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 Delta m(41)(2) are obtained.",
