Precision Analysis of the Xe 136 Two-Neutrino β β Spectrum in KamLAND-Zen and Its Impact on the Quenching of Nuclear Matrix Elements
© 2019 authors. Published by the American Physical Society. We present a precision analysis of the Xe136 two-neutrino ββ electron spectrum above 0.8 MeV, based on high-statistics data obtained with the KamLAND-Zen experiment. An improved formalism for the two-neutrino ββ rate allows us to measure th...
