Abstract

We have built a low background detector, a time projection chamber surrounded by an active anti-Compton, to measure the v̄_ee^- elastic cross section down to the antineutrino energy of 900 keV. With our detector, running at 18 m from the core of a nuclear reactor in Bugey, we could detect reactor antineutrinos by measuring both the energy and the direction of the recoiling electrons. We report here on a first analysis of the data using an automatic scanning procedure. The results we obtain are 1.5σ higher than the ones predicted by the standard model.
