Description

The Daya Bay and PROSPECT experiments have made world-leading measurements of the $^{235}$U antineutrino fission spectra using liquid scintillator detectors located at nuclear reactors. The Daya Bay experiment has deconvolved a $^{235}$U spectrum from $\sim$3.5 million detected antineutrinos generated from power reactors with an isotopic mixture of fuels, and PROSPECT has detected $\sim$50,000 antineutrinos generated by a research reactor highly enriched in $^{235}$U. Combining the high-statistics Daya Bay measurement and PROSPECT's direct $^{235}$U measurement we derive a more precise measurement of the $^{235}$U antineutrino spectrum and improve the deconvolution of the power reactor fission spectrum into its individual isotopic components. In this talk, I will present the current status of the joint spectral analyses between these experiments.
