Simultaneous detection of boosted dark matter and neutrinos from the semi-annihilation at DUNE | | Mayumi Aoki

1 Sep 2023 | | Abstract: | Dark matter direct detection experiments impose the strong bounds on thermal
dark matter scenarios. The bound can naturally be evaded if the cross section
is momentum transfer dependent or velocity dependent. One can test such thermal
dark matter scenarios if dark matter particles are boosted by some mechanism.
In this work, we consider a specific semi-annihilation $chichi o
uoverline{chi}$ where $chi$ ($overline{chi}$) is dark matter (anti-dark
matter), and search for simultaneous detection of the neutrino and the boosted
dark matter in the final state at DUNE. We find that the energies of the
neutrino and boosted dark matter are reconstructed well due to the precise
angular resolution of the DUNE detector. In addition, we find that both signals
can be testable at DUNE if the dark matter mass is below 30 GeV, and the
scattering cross section is momentum transfer dependent. | | Source: | arXiv, 2309.00395 | | Services: | Forum | Review | PDF | Favorites | |
