An Indirect Dark Matter Search Using Cosmic-Ray Antiparticles with GAPS

Experiments aiming to directly detect dark matter (DM) particles have yet to make robust detections, thus underscoring the need for complementary approaches such as searches for new particles at colliders, and indirect DM searches in cosmic-ray spect

Publikováno v: Journal of Space Weather and Space Climate, Vol 12, p 37 (2022)

Solar modulation of galactic cosmic rays around the solar minimum in 2019–2020 looks different in the secondary neutrons and muons observed at the ground. To compare the solar modulation of primary cosmic rays in detail, we must remove the possible
