Double Chooz is a reactor experiment designed to detect neutrino oscillations driven by the yet undetermined leptonic mixing angle theta_13. In the past, reactor experiments like CHOOZ and Palo Verde gave strong constraints on theta_13 pointing towards a small, or even zero, theta_13 scenario. Recently, accelerator experiments like MINOS and T2K published indications that favor a non-zero theta_13 value. In this seminar we shall present the first results from Double Chooz based on the analysis of the first 101 days of data taking operating with a single, far detector. Perspectives and next steps of this quest will also be
reviewed.
