Investigating an angular correlation between nearby starburst galaxies and UHECRs with the Telescope Array experiment [PDF]

EPJ Web of Conferences, 2019
The arrival directions of cosmic rays detected by the Pierre Auger Observatory (Auger) with energies above 39 EeV were recently reported to correlate with the positions of 23 nearby starburst galaxies (SBGs): in their best-fit model, 9.7% of the cosmic ...

Reverse direct detection: Cosmic ray scattering with light dark matter [PDF]

Physical Review D, 2018
Sub-GeV dark matter candidates are of increasing interest, because long-favored candidates such as GeV-scale WIMPs have not been detected. For low-mass dark matter, model-independent constraints are weak or nonexistent.

Design and operation of a 1500-m laser strainmeter installed at an underground site in Kamioka, Japan

Earth, Planets and Space, 2017
A laser strainmeter with a 1500-m baseline was constructed at an underground site in Kamioka, Gifu Prefecture, Japan, and has been operating since August 2016. The laser interferometer measures the change in distance between two retroreflectors housed in

Muon g − 2 in gauge mediation without SUSY CP problem

Journal of High Energy Physics, 2021
We discuss gauge mediated supersymmetry breaking models which explain the observed muon anomalous magnetic moment and the Higgs boson mass simultaneously.

The Cosmic Ray Energy Spectrum between 2 PeV and 2 EeV Observed with the TALE Detector in Monocular Mode [PDF]

Astrophysical Journal, 2018
We report on a measurement of the cosmic ray energy spectrum by the Telescope Array Low-Energy Extension (TALE) air fluorescence detector (FD). The TALE air FD is also sensitive to the Cherenkov light produced by shower particles. Low-energy cosmic rays,

Cosmic-ray ionisation in circumstellar discs [PDF]

Astronomy & Astrophysics, 2018
Context. Galactic cosmic rays (CRs) are a ubiquitous source of ionisation of the interstellar gas, competing with UV and X-ray photons as well as natural radioactivity in determining the fractional abundance of electrons, ions, and charged dust grains in

Dark cosmic rays

Physics Letters B, 2017
If dark matter particles have an electric charge, as in models of millicharged dark matter, such particles should be accelerated in the same astrophysical accelerators that produce ordinary cosmic rays, and their spectra should have a predictable rigidity dependence. Depending on the charge, the resulting "dark cosmic rays" can be detected as muon-like
