Goal

Study processes expected to deposit larger energies > 1MeV and/or undergo multiple interactions.

Should distinguish between CR (heavy non-rel DM) and decay/inelastic boosted DM (two-three DM states that can decay into each other) (i.e., do the two need to be searched for in different ways).

CR-BDM will have an additional daily modulation signature as it passes through the earth. Interesting results could come from comparing observations (or lack thereof) in the Southern Hemisphere with those in the Northern. The LAB detector may also play a role, as previous constraints have been set by DUNE, MiniBoone and Super-K (all of these have high energy threshold, might we gain something if ours is lower?)

Investigated processes

• Attenuation through the Earth and resulting modulation signal (nb: likely an intensive theoretical task)

• Understanding of influence of usual detector effects

• Influence of energy thresholds

• Influence of geographical position

• Influence of a particular target (NaI and/or LAB)
