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…
Search for Low-energy Electron Antineutrinos in KamLAND Associated with Gravitational Wave Events
S. Abe, S. Asami, A. Gando +65
We present the results of a search for MeV-scale electron antineutrino events in KamLAND in coincident with the 60 gravitational wave events/candidates reported by the LIGO/Virgo c…
Front-end-Electronics for the SiPM-readout gaseous TPC for neutrinoless double beta decay search
K. Z. Nakamura, S. Ban, A. K. Ichikawa +7
We have developed a dedicated front-end-electronics board for a high-pressure xenon gas time projection chamber for a neutrinoless double-beta decay search. The ionization signal i…
AXEL: High-pressure Xe gas TPC for BG-free decay search
S. Obara, S. Ban, M. Hirose +15
AXEL is a high-pressure xenon gas time projection chamber for neutrinoless double-beta decay (0n2b) search. The AXEL has a unique readout system called ELCC which has a cellular st…
Scintillation Balloon for Neutrinoless Double-Beta Decay Search with Liquid Scintillator Detectors
S. Obara, Y. Gando, K. Ishidoshiro
Environmental radioactivity is a dominant background for rare decay search experiments, and it is difficult to completely remove such an impurity from detector vessels. We propose…
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…
