New Light on Dark Extended Lenses with the Roman Space Telescope
William DeRocco, Nolan Smyth, Volodymyr Takhistov
The Roman Space Telescope's Galactic Bulge Time Domain Survey will constitute the most sensitive microlensing survey of the Galactic Bulge to date, opening up new opportunities to…
Non-Canonical Nucleon Decays as Window into Light New Physics
Kåre Fridell, Chandan Hati, Volodymyr Takhistov
Nucleon decays are generic predictions of motivated theories, including those based on the unification of forces and supersymmetry. We demonstrate that non-canonical nucleon decays…
Primordial Black Hole Sterile Neutrinogenesis: Sterile Neutrino Dark Matter Production Independent of Couplings
Muping Chen, Graciela B. Gelmini, Philip Lu +1
Sterile neutrinos (s) are well-motivated and actively searched for hypothetical neutral particles that would mix with the Standard Model active neutrinos. They are considered…
Atmospheric neutrino oscillation analysis with neutron tagging and an expanded fiducial volume in Super-Kamiokande I-V
Kamiokande Collaboration, T. Wester, K. Abe +233
We present a measurement of neutrino oscillation parameters with the Super-Kamiokande detector using atmospheric neutrinos from the complete pure-water SK I-V (April 1996-July 2020…
Measurement of the neutrino-oxygen neutral-current quasielastic cross section using atmospheric neutrinos in the SK-Gd experiment
S. Sakai, K. Abe, C. Bronner +233
We report the first measurement of the atmospheric neutrino-oxygen neutral-current quasielastic (NCQE) cross section in the gadolinium-loaded Super-Kamiokande (SK) water Cherenkov…
Coexistence Test of Primordial Black Holes and Particle Dark Matter from Diffractive Lensing
Han Gil Choi, Sunghoon Jung, Philip Lu +1
If dark matter (DM) consists of primordial black holes (PBHs) and particles simultaneously, PBHs are generically embedded within particle DM halos. Such ``dressed PBHs'' (dPBHs) ar…
Search for Periodic Time Variations of the Solar B Neutrino Flux between 1996 and 2018 in Super-Kamiokande
K. Abe, C. Bronner, Y. Hayato +233
We report a search for time variations of the solar B neutrino flux using 5804 live days of Super-Kamiokande data collected between May 31, 1996, and May 30, 2018. Super-Kamiok…
Effects of Finite Material Size On Axion-magnon Conversion
So Chigusa, Asuka Ito, Kazunori Nakayama +1
Magnetic materials are particularly favorable targets for detecting axions interacting with electrons because the collective excitation of electron spins, the magnon, can be excite…
Axion-like Universal Gravitational Wave Interpretation of Pulsar Timing Array Data
Kaloian D. Lozanov, Shi Pi, Misao Sasaki +2
Formation of cosmological solitons is generically accompanied by production of gravitational waves (GWs), with a universal GW background expected at frequency scales below that of…
Universal Gravitational Waves from Interacting and Clustered Solitons
Kaloian D. Lozanov, Misao Sasaki, Volodymyr Takhistov
Causal soliton formation (e.g. oscillons, Q-balls) in the primordial Universe is expected to give rise to a universal gravitational wave (GW) background, at frequencies smaller tha…
Primordial Black Hole Neutrinogenesis of Sterile Neutrino Dark Matter
Muping Chen, Graciela B. Gelmini, Philip Lu +1
Sterile neutrinos are well-motivated and actively searched for new particles that would mix with the active neutrinos. We study their phenomenology when they are produced in the ev…
Regurgitated Dark Matter
TaeHun Kim, Philip Lu, Danny Marfatia +1
We present a new paradigm for the production of the dark matter (DM) relic abundance based on the evaporation of early Universe primordial black holes (PBHs) themselves formed from…
Hunting Nonstandard Neutrino Interactions and Leptoquarks in Dark Matter Experiments
Thomas Schwemberger, Volodymyr Takhistov, Tien-Tien Yu
Next generation direct dark matter (DM) detection experiments will have unprecedented capabilities to explore coherent neutrino-nucleus scattering (CENS) complementary to dedica…
Detection of Bosenovae with Quantum Sensors on Earth and in Space
Jason Arakawa, Joshua Eby, Marianna S. Safronova +2
In a broad class of theories, the accumulation of ultralight dark matter (ULDM) with particles of mass leads the to formation of long-l…
Search for astrophysical electron antineutrinos in Super-Kamiokande with 0.01wt% gadolinium-loaded water
M. Harada, K. Abe, C. Bronner +238
We report the first search result for the flux of astrophysical electron antineutrinos for energies O(10) MeV in the gadolinium-loaded Super-Kamiokande (SK) detector. In June 2020,…
Universal Gravitational Wave Signatures of Cosmological Solitons
Kaloian D. Lozanov, Misao Sasaki, Volodymyr Takhistov
Cosmological solitonic objects such as monopoles, cosmic strings, domain walls, oscillons and Q-balls often appear in theories of the early Universe. We demonstrate that such scena…
