Light Sterile Neutrino Search From Daya Bay

The standard three-neutrino mixing framework works very well in most of the neutrino oscillation experiments except for several “anomalies”, which may be caused by light sterile neutrinos at eV or sub-eV scale. With millions of electron antineutrino candidates accumulated by multiple antineutrino detectors at hundred meters away from the reactors, DayaBay has the best sensitivity for light sterile neutrino search in the |∆m412|< 0.2 eV2 region. In addition, based on the 3(active)+1(sterile) - neutrino mixing model, a combined analysis using DayaBay, Bugey-3 and MINOS experimental data is performed to constrain the sterile neutrino mixing phase space and compare with the results from the LSND and MiniBooNEexperiments.
