Review of Atmospheric Neutrino Results from Super-Kamiokande
Volodymyr Takhistov
While neutrino physics enters precision era, several important unknowns remain. Atmospheric neutrinos allow to simultaneously test key oscillation parameters, with Super-Kamiokande…
Neutron-Antineutron Oscillation Search using a 0.37 MegatonYear Exposure of Super-Kamiokande
Kamiokande Collaboration, K. Abe, C. Bronner +196
As a baryon number violating process with , neutron-antineutron oscillation () provides a unique test of baryon number conservation. We have performed a search fo…
Contribution of Secondary Neutrinos from Line-of-sight Cosmic Ray Interactions to the IceCube Diffuse Astrophysical Flux
Alina Kochocki, Volodymyr Takhistov, Alexander Kusenko +1
In ten years of observations, the IceCube neutrino observatory has revealed a neutrino sky in tension with previous expectations for neutrino point source emissions. Astrophysical…
Search for solar electron anti-neutrinos due to spin-flavor precession in the Sun with Super-Kamiokande-IV
Kamiokande Collaboration, K. Abe, C. Bronner +197
Due to a very low production rate of electron anti-neutrinos () via nuclear fusion in the Sun, a flux of solar is unexpected. An appearance of in solar…
Search for proton decay via and with an enlarged fiducial volume in Super-Kamiokande I-IV
Kamiokande Collaboration, A. Takenaka, K. Abe +211
We have searched for proton decay via and modes with the enlarged fiducial volume data of Super-Kamiokande from April 1996 to May 2018, which correspond…
Testing Stochastic Gravitational Wave Signals from Primordial Black Holes with Optical Telescopes
Sunao Sugiyama, Volodymyr Takhistov, Edoardo Vitagliano +3
Primordial black holes (PBHs) can constitute the predominant fraction of dark matter (DM) if PBHs reside in the currently unconstrained "sublunar" mass range. PBHs originating from…
Gas Heating from Spinning and Non-Spinning Evaporating Primordial Black Holes
Ranjan Laha, Philip Lu, Volodymyr Takhistov
Primordial black holes (PBHs) from the early Universe constitute a viable dark matter (DM) candidate and can span many orders of magnitude in mass. Light PBHs with masses around $1…
Constraining Primordial Black Holes with Dwarf Galaxy Heating
Philip Lu, Volodymyr Takhistov, Graciela B. Gelmini +3
Black holes formed in the early universe, prior to the formation of stars, can exist as dark matter and also contribute to the black hole merger events observed in gravitational wa…
Scalar Direct Detection: In-Medium Effects
Graciela B. Gelmini, Volodymyr Takhistov, Edoardo Vitagliano
A simple extension of the Standard Model consists of a scalar field that can potentially constitute the dark matter (DM). Significant attention has been devoted to probing light $\…
Note on Thermalization of Non-resonantly Produced Sterile Neutrinos
Graciela B. Gelmini, Philip Lu, Volodymyr Takhistov
Using an analytic treatment, we discuss the parameter regions of large active-sterile neutrino mixing angles where sterile neutrinos produced in non-resonant flavour oscillations c…
Probing dark photons with plasma haloscopes
Graciela B. Gelmini, Alexander J. Millar, Volodymyr Takhistov +1
Dark photons (DPs) produced in the early Universe are well-motivated dark matter (DM) candidates. We show that the recently proposed tunable plasma haloscopes are particularly adva…
Indirect Search for Dark Matter from the Galactic Center and Halo with the Super-Kamiokande Detector
Kamiokande Collaboration, K. Abe, C. Bronner +269
We present a search for an excess of neutrino interactions due to dark matter in the form of Weakly Interacting Massive Particles (WIMPs) annihilating in the galactic center or hal…
Big Bang Nucleosynthesis constraints on sterile neutrino and lepton asymmetry of the Universe
Graciela B. Gelmini, Masahiro Kawasaki, Alexander Kusenko +2
We consider the cosmological effects of sterile neutrinos with the masses of MeV. The decay of sterile neutrinos changes the thermal history of the Universe and affects…
Supernova Model Discrimination with Hyper-Kamiokande
Jost Migenda
Supernovae are among the most magnificent events in the observable universe. They produce many of the chemical elements necessary for life to exist and their remnants---neutron sta…
Search for proton decay into three charged leptons in 0.37 megaton-years exposure of the Super-Kamiokande
Kamiokande Collaboration, M. Tanaka, K. Abe +178
A search for proton decay into three charged leptons has been performed by using 0.37Mtonyears of data collected in Super-Kamiokande. All possible combinations of electr…
Exploring Primordial Black Holes from the Multiverse with Optical Telescopes
Alexander Kusenko, Misao Sasaki, Sunao Sugiyama +3
Primordial black holes (PBHs) are a viable candidate for dark matter if the PBH masses are in the currently unconstrained "sublunar" mass range. We revisit the possibility that PBH…
