TL;DR: An improved search for neutrinoless double-beta (0νββ) decay of ^{136}Xe in the KamLAND-Zen experiment is presented and a significant reduction of the xenon-loaded liquid scintillator contaminant identified in previous searches is achieved.

Publisher's Note: Search for Majorana Neutrinos Near the Inverted Mass Hierarchy Region with KamLAND-Zen [Phys. Rev. Lett. 117, 082503 (2016)].

TL;DR: This corrects the article DOI: 10.1103/PhysRevLett.117.082503 to reflect that the paper was originally published in Physical Review Letters, not RevLett, rather than Science.
Journal ArticleDOI
Double beta decays of 100Mo
Hiroyasu Ejiri,Ken-Ichi Fushimi,T. Kamada,H. Kinoshita,H. Kobiki,Hideaki Ohsumi,Kei Okada,H. Sano,T. Shibata,Tatsushi Shima,N. Tanabe,J. Tanaka,T. Taniguchi,Takayuki Watanabe,N. Yamamoto +14 more
TL;DR: In this paper, a finite half-life of T 2v 1 2 =(1.15 + 0.30 − 0.20 )×10 19 yr (68% CL ) for 2νββ decay and the most stringent lower limit of T 0v 1/2 > 4.7 × 10 21 yr ( 68% CL ), for the 0v ββ decay were obtained.
Journal ArticleDOI
Search for neutrino-less double beta decay of 48Ca by CaF2 scintillator
Izumi Ogawa,Ryuta Hazama,H. Miyawaki,S. Shiomi,N. Suzuki,Y. Ishikawa,G. Kunitomi,Yukichi Tanaka,M. Itamura,K. Matsuoka,S. Ajimura,Tadamitsu Kishimoto,H. Ejiri,Nobuyuki Kudomi,Kyo Kume,H. Ohsumi,Ken-Ichi Fushimi +16 more
TL;DR: In this paper, a lower limit for the half-life of the neutrino-less double beta decay of 48 Ca was derived by a Monte Carlo simulation using the measured activities of 214 Bi and 220 Rn inside CaF 2 crystals.
Journal ArticleDOI
Application of a large-volume NaI scintillator to search for dark matter.
Ken-Ichi Fushimi,Hiroyasu Ejiri,H. Kinoshita,Nobuyuki Kudomi,Kyo Kume,Keitaro Nagata,H. Ohsumi,Kei Okada,H. Sano,Junichi Tanaka +9 more
TL;DR: The present Rapid Communication reports the first application of a huge scintillation detector to search for the nonbaryonic dark matter (DM) by investigating directly the elastic scattering of DM by ' I and Na nuclei in the NaI detector.
