Double Chooz publishes new measurement of θ13 and reactor neutrinos flux

Since the detectors interruption in early 2018, Double Chooz international collaboration continues its data analysis in order to find the most accurate value of θ₁₃, the third and last mixing angle of the neutrino oscillation process. Researchers have also measured with unprecedented precision the neutrinos flux emitted by the nuclear fission reactors. Those results were published in “Nature Physics” on the 20th of April, 2020. More informations on the IN2P3 website.

Double Chooz collaboration unite over a hundred of researchers from 7 countries (France, Germany, Brazil, Spain, USA, Japan, and Russia). It received a funding from the Labex UnivEarthS, under the Frontier project F2.
