Session and Location
Wednesday Session, Poster Wall #4 (Robert-Schumann-Room)
The poster presents the latest results of the reactor antineutrino flux and spectrum at Daya Bay. The antineutrinos were generated by six nuclear reactors with 2.9 GW thermal power each and detected by eight antineutrino detectors deployed in two near and one far underground experimental halls. The Inverse beta decay reaction yield was measured and compared with the reactor flux predictions. A deviation in the measured positron prompt energy spectrum was found with the comparison to the reactor flux predictions. In particular, an excess of events in the region of 4-6 MeV was revealed and characterized. A reactor antineutrino spectrum of IBD reactions is extracted for model-independent predictions.
