An axion constraint from the diffuse supernova neutrino background indicated by Super-Kamiokande
Kanji Mori, Tomoya Takiwaki, Kazunori Kohri +1
Recently, the Super-Kamiokande Collaboration reported an indication of the diffuse supernova neutrino background (DSNB) with a statistical significance of . Motivated by this…
Rotation-induced Relaxation of Supernova Constraints on Axionlike Particles
Tsurugi Takata, Kanji Mori, Ko Nakamura +1
We study how rotation modifies the constraints on MeV-scale axion-like particles (ALPs) coupled to photons derived from SN 1987A. We constrain the ALP parameter space based on both…
Verifying the failing supernova constraint on dark photons with two-dimensional hydrodynamic simulations
Kanji Mori, Tomoya Takiwaki, Kazunori Kohri
Recent studies on the dark photon (DP) production in collapsing stars argue that the cooling effect induced by DPs can hinder supernova explosions and lead to a ``failing supernova…
Long-term neutrino emission from a core-collapse supernova with axion-photon coupling
Masamitsu Mori, Kanji Mori
We perform long-term general-relativistic neutrino-radiation hydrodynamic simulations for core-collapse supernovae (CCSNe) which include the cooling effect induced by the coupling…
Impacts of axion cooling on the direct detection of supernova axions
Kanji Mori, Masamitsu Mori
Core-collapse supernovae provide a unique opportunity to probe axions because they can be a copious source of the particles. It has recently been proposed that axion helioscopes ca…
Core-collapse supernova explosions hindered by eV-mass sterile neutrinos
Kanji Mori, Tomoya Takiwaki, Kazunori Kohri +1
Light sterile neutrinos, , are often introduced to explain an anomalous deficit in the electron antineutrino flux from nuclear reactors. If they exist, sterile neutrinos would…
Three-dimensional core-collapse supernova models with phenomenological treatment of neutrino flavor conversions
Kanji Mori, Tomoya Takiwaki, Kei Kotake +1
We perform three-dimensional supernova simulations with a phenomenological treatment of neutrino flavor conversions. We show that the explosion energy can increase to as high as ~1…
Progenitor Dependence of Neutrino-driven Supernova Explosions with the Aid of Heavy Axion-like Particles
Tsurugi Takata, Kanji Mori, Ko Nakamura +1
We perform spherically symmetric simulations of core-collapse supernovae with the aid of heavy axion-like particles (ALPs) which interact with photons and redistribute energy withi…
