A Search for Charged Excitation of Dark Matter with the KamLAND-Zen Detector
S. Abe, S. Asami, A. Gando +68
There are many theories where a dark matter particle is part of a multiplet with an electrically charged state. If WIMP dark matter () is accompanied by a charged excited st…
Precision Analysis of the Xe Two-Neutrino Spectrum in KamLAND-Zen and Its Impact on the Quenching of Nuclear Matrix Elements
Zen Collaboration
We present a precision analysis of the Xe two-neutrino electron spectrum above 0.8 MeV, based on high-statistics data obtained with the KamLAND-Zen experiment. An impr…
Search for Majorana Neutrinos near the Inverted Mass Hierarchy Region with KamLAND-Zen
Zen Collaboration
We present an improved search for neutrinoless double-beta () decay of Xe in the KamLAND-Zen experiment. Owing to purification of the xenon-loaded liquid scintillator…
Search for double-beta decay of 136Xe to excited states of 136Ba with the KamLAND-Zen experiment
Zen Collaboration, K. Asakura, A. Gando +42
A search for double-beta decays of 136Xe to excited states of 136Ba has been performed with the first phase data set of the KamLAND-Zen experiment. The 0+1, 2+1 and 2+2 transitions…
