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…

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…

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…

Low background measurement in CANDLES-III for studying the neutrino-less double beta decay of Ca

S. Ajimura, W. M. Chan, K. Ichimura +65

We developed a CANDLES-III system to study the neutrino-less double beta (0) decay of Ca. The proposed system employs 96 CaF scintillation crystals (305 kg) with…

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…
