Description

The search for the particle nature of dark matter has entered a new era of multi-messenger astrophysics. We are developing a novel tracking-calorimeter to explore two promising indirect detection channels: low-energy cosmic antinuclei and MeV gamma rays. We innovatively hybridize the detection technique using exotic atomic formation/decay and multi-layer Compton imaging into one detector system, and then are able to precisely measure the cosmic antinuclei in the unexplored low-energy range and MeV gamma with a sensitivity one order of magnitude beyond the current best.

This presentation will discuss the potentials of low-energy antinuclei and MeV gamma for new physics search, and then report the development of the novel tracking-calorimeter including a pathfinder and the first compact payload for the microsatellite mission.
