Description
TAO, a satellite detector of the JUNO experiment, is designed to measure the reactor antineutrino energy spectrum with high resolution. This measurement provides a critical reference for the JUNO analysis. The inverse beta decay (IBD) spectrum carries valuable information on the fine structure of the reactor antineutrino spectrum. To extract the IBD spectrum, an event selection algorithm has been developed, which includes a muon veto as well as cuts on energy, multiplicity, fiducial volume, and distance. TAO started its first physics data-taking phase shortly after the Spring Festival of 2026. Using these first official data, the IBD and accidental event spectra have been successfully obtained for both reactor-on and reactor-off periods. In addition, the efficiency of the selection process has been evaluated. This poster presents the details of the above analysis as the first physics analysis from the TAO detector.
