Development of a method to measure trace level of uranium and thorium in scintillation films
K. Ichimura, K. Chiba, Y. Gando +7
We have established a method to measure picograms-per-gram (pg g) levels of U and Th in scintillation films by combining the dry ashing method and inductivel…
Search for Charged Excited States of Dark Matter with KamLAND-Zen
Zen collaboration, S. Abe, M. Eizuka +64
Particle dark matter could belong to a multiplet that includes an electrically charged state. WIMP dark matter () accompanied by a negatively charged excited state ()…
Development of a low-background HPGe detector at Kamioka Observatory
K. Ichimura, H. Ikeda, Y. Kishimoto +9
A new ultra-low background high-purity germanium (HPGe) detector has been installed at the Kamioka underground experimental site. The background count rate in the energy range from…
Measurement of cosmic-ray muon spallation products in a xenon-loaded liquid scintillator with KamLAND
Zen Collaboration, S. Abe, S. Asami +63
Cosmic-ray muons produce various radioisotopes when passing through material. These spallation products can be backgrounds for rare event searches such as in solar neutrino, double…
First measurement of the strange axial coupling constant using neutral-current quasielastic interactions of atmospheric neutrinos at KamLAND
KamLAND Collaboration, S. Abe, S. Asami +61
We report a measurement of the strange axial coupling constant using atmospheric neutrino data at KamLAND. This constant is a component of the axial form factor of the neut…
Abundances of uranium and thorium elements in Earth estimated by geoneutrino spectroscopy
S. Abe, S. Asami, M. Eizuka +64
The decay of the primordial isotopes , , , and have contributed to the terrestrial heat budget throughout t…
Search for supernova neutrinos and constraint on the galactic star formation rate with the KamLAND data
S. Abe, S. Asami, M. Eizuka +63
We present the results of a search for core-collapse supernova neutrinos, using long-term KamLAND data from 2002 March 9 to 2020 April 25. We focus on the electron antineutrinos em…
Search for the Majorana Nature of Neutrinos in the Inverted Mass Ordering Region with KamLAND-Zen
Zen Collaboration, S. Abe, S. Asami +70
The KamLAND-Zen experiment has provided stringent constraints on the neutrinoless double-beta () decay half-life in Xe using a xenon-loaded liquid scintillator. We re…
KamLAND's search for correlated low-energy electron antineutrinos with astrophysical neutrinos from IceCube
S. Abe, S. Asami, M. Eizuka +66
We report the results of a search for MeV-scale astrophysical neutrinos in KamLAND presented as an excess in the number of coincident neutrino interactions associated with the publ…
A search for correlated low-energy electron antineutrinos in KamLAND with gamma-ray bursts
S. Abe, S. Asami, A. Gando +64
We present the results of a time-coincident event search for low-energy electron antineutrinos in the KamLAND detector with gamma-ray bursts from the Gamma-ray Coordinates Network…
