Measurement of the cosmogenic neutron yield in Super-Kamiokande with gadolinium loaded water
Kamiokande Collaboration, M. Shinoki, K. Abe +238
Cosmic-ray muons that enter the Super-Kamiokande detector cause hadronic showers due to spallation in water, producing neutrons and radioactive isotopes. Those are a major backgrou…
Revisiting Tests of Lorentz Invariance with Gamma-ray Bursts: Effects of Intrinsic Lags
Valeri Vardanyan, Volodymyr Takhistov, Metin Ata +1
Due to their cosmological distances high-energy astrophysical sources allow for unprecedented tests of fundamental physics. Gamma-ray bursts (GRBs) comprise among the most sensitiv…
Signatures of a High Temperature QCD Transition in the Early Universe
Philip Lu, Volodymyr Takhistov, George M. Fuller

Search for proton decay via in 0.37 megaton-years exposure of Super-Kamiokande
Kamiokande Collaboration, R. Matsumoto, K. Abe +229
We searched for proton decay via in 0.37\,Mtonyears of data collected between 1996 and 2018 from the Super-Kamiokande water Cherenkov experiment. The selection…
Revealing Dark Matter Dress of Primordial Black Holes by Cosmological Lensing
Masamune Oguri, Volodymyr Takhistov, Kazunori Kohri
Stellar-mass primordial black holes (PBHs) from the early Universe can directly contribute to the gravitational wave (GW) events observed by LIGO, but can only comprise a subdomina…
