Description
The nature of dark matter remains unknown. In the particle hypothesis, the detection of antinuclei by space-borne experiments near Earth has been identified as a potential smoking gun for dark matter signals. Due to their astrophysical background being highly suppressed for kinetic energies below 1 GeV/c, antinuclei represent an attractive search channel. Recently, theoretical efforts have been made to introduce new channels for antinuclei production via beauty-hadrons decays. These channels could contribute to the signal of Dark Matter but have never been observed and require experimental validation. The Large Hadron Collider (LHC) offers the ideal environment for these studies and for the determination of the branching ratio of beauty hadron decay to anti-nuclei; however, to drive the research in this field, reliable estimates of the possible branching ratios are needed. In this contribution we present a prediction of the $\overline{\Lambda}_b \rightarrow \overline{\rm{d}} + X$ and $\rm{B}^-\rightarrow \overline{d} + X$ branching ratios. \texttt{PYTHIA} is used to simulate the production of these particles and their respective decays. A state-of-the-art coalescence model is applied to the resulting antinucleons to produce antideuterons. Based on this first estimate of the branching ratios, we also discuss the feasibility of measuring these new channels at the LHC.
