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.
Journal ArticleDOI
Imaginary chemical potential approach for the pseudocritical line in the QCD phase diagram with clover-improved Wilson fermions
Keitaro Nagata,Atsushi Nakamura +1 more
TL;DR: In this paper, the phase diagram of the pseudo-critical line of the Polyakov loop was investigated in the imaginary chemical potential (ICP)-based lattice QCD simulation at an intermediate quark mass on a $8^3\times 4$ lattice.
Journal ArticleDOI

Hiroyasu Ejiri,Ken-Ichi Fushimi,K. Hayashi,Ryuta Hazama,Tadafumi Kishimoto,Nobuyuki Kudomi,Kyo Kume,Keitaro Nagata,H. Ohsumi,Kei Okada,Tatsushi Shima,Junki Tanaka +11 more
TL;DR: In this article, the neutrino-less double beta decays (0νββ) of 100Mo were made by means of ELEGANT V. Most stringent lower limits on the half-lives for the ground-state transition were obtained for the 0νβα processes as T 1 2 0ν (m ν ) > 5.2 × 10 22 y, T 1 1 2 ε (λ) > 3.9 × 1022 y and T 1 two ε(ε)-ε (δ)-δ ≥ 5.1
Journal ArticleDOI
Lee-Yang zero distribution of high temperature QCD and the Roberge-Weiss phase transition
TL;DR: Canonical partition functions and Lee-Yang zeros of QCD at finite density and high temperature are studied in this article, where the authors show that the canonical partition functions follow the Gaussian distribution of the baryon number, and the accumulation of these canonical partitions exhibit the first-order Roberge-Weiss phase transition.
Journal ArticleDOI
Towards extremely dense matter on the lattice
Keitaro Nagata,Shinji Motoki,Yoshiyuki Nakagawa,Atsushi Nakamura,Atsushi Nakamura,Takuya Saito +5 more
TL;DR: Nagata et al. as discussed by the authors proposed the XQCD-J Collaboration (XQCD J Collaboration) with the aim of improving the quality of information in Japan.
