Search for neutrinoless quadruple beta decay of Xe in XMASS-I
XMASS Collaboration, K. Abe, K. Hiraide +34
A search for the neutrinoless quadruple beta decay of Xe was conducted with the liquid-xenon detector XMASS-I using of the exposure. The…
Direct dark matter search by annual modulation with 2.7 years of XMASS-I data
XMASS Collaboration, K. Abe, K. Hiraide +39
An annual modulation signal due to the Earth orbiting around the Sun would be one of the strongest indications of the direct detection of dark matter. In 2016, we reported a search…
A direct dark matter search in XMASS-I
XMASS Collaboration, K. Abe, K. Hiraide +39
A search for dark matter using an underground single-phase liquid xenon detector was conducted at the Kamioka Observatory in Japan, particularly for Weakly Interacting Massive Part…
Development of low-background photomultiplier tubes for liquid xenon detectors
XMASS Collaboration, K. Abe, Y. Chen +36
We successfully developed a new photomultiplier tube (PMT) with a three-inch diameter, convex-shaped photocathode, R13111. Its prominent features include good performance and ultra…
Search for event bursts in XMASS-I associated with gravitational-wave events
XMASS Collaboration, K. Abe, K. Hiraide +34
We performed a search for event bursts in the XMASS-I detector associated with 11 gravitational-wave events detected during LIGO/Virgo's O1 and O2 periods. Simple and loose cuts we…
Development of low radioactivity photomultiplier tubes for the XMASS-I detector
XMASS Collaboration, K. Abe, K. Hiraide +39
XMASS-I is a single-phase liquid xenon detector whose purpose is direct detection of dark matter. To achieve the low background requirements necessary in the detector, a new model…
Search for WIMP-Xe inelastic scattering with particle identification in XMASS-I
XMASS Collaboration, T. Suzuki, K. Abe +34
A search for Weakly Interacting Massive Particles (WIMPs) was conducted with the single-phase liquid-xenon detector XMASS through inelastic scattering in which Xe nuclei we…
A measurement of the scintillation decay time constant of nuclear recoils in liquid xenon with the XMASS-I detector
XMASS Collaboration, K. Abe, K. Hiraide +35
We report an in-situ measurement of the nuclear recoil (NR) scintillation decay time constant in liquid xenon (LXe) using the XMASS-I detector at the Kamioka underground laboratory…
Search for dark matter in the form of hidden photons and axion-like particles in the XMASS detector
XMASS Collaboration, K. Abe, K. Hiraide +35
Hidden photons and axion-like particles are candidates for cold dark matter if they were produced non-thermally in the early universe. We conducted a search for both of these boson…
Direct dark matter searches with the full data set of XMASS-I
XMASS Collaboration, K. Abe, K. Hiraide +29
Various WIMP dark matter searches using the full data set of XMASS-I, a single-phase liquid xenon detector, are reported in this paper. Stable XMASS-I data taking accumulated a tot…
A measurement of the time profile of scintillation induced by low energy gamma-rays in liquid xenon with the XMASS-I detector
XMASS Collaboration, H. Takiya, K. Abe +36
We report the measurement of the emission time profile of scintillation from gamma-ray induced events in the XMASS-I 832 kg liquid xenon scintillation detector. Decay time constant…
Improved search for two-neutrino double electron capture on Xe and Xe using particle identification in XMASS-I
XMASS Collaboration, K. Abe, K. Hiraide +39
We conducted an improved search for the simultaneous capture of two -shell electrons on the Xe and Xe nuclei with emission of two neutrinos using 800.0 days of d…
Search for solar Kaluza-Klein axion by annual modulation with the XMASS-I detector
XMASS Collaboration, N. Oka, K. Abe +39
In theories with the large extra dimensions beyond the standard 4-dimensional spacetime, axions could propagate in such extra dimensions, and acquire Kaluza-Klein (KK) excitations.…
Search for two-neutrino double electron capture on Xe with the XMASS-I detector
XMASS Collaboration, K. Abe, K. Hiraide +40
Double electron capture is a rare nuclear decay process in which two orbital electrons are captured simultaneously in the same nucleus. Measurement of its two-neutrino mode would p…
Detectability of galactic supernova neutrinos coherently scattered on xenon nuclei in XMASS
XMASS Collaboration
The coherent elastic neutrino-nucleus scattering (CEvNS) plays a crucial role at the final evolution of stars. The detection of it would be of importance in astroparticle physics.…
