We suggest to use the intranuclear cascade model (INC) for simulation of antideutron-nucleus inelastic interaction in the region of antideutron energies of $100$ MeV/n $\le T_{kin}\le 25-30$ GeV/n for a wide range of target nuclei. With the…

The discovery of a single anti-helium nucleus in the cosmic ray flux would definitely point toward the existence of stars and even of entire galaxies made of anti-matter. The presence of anti-nuclei in cosmic rays has actually profound…
NEUT is a neutrino-nucleus interaction simulation. It can be used to simulate interactions for neutrinos with between 100 MeV and a few TeV of energy. NEUT is also capable of simulating hadron interactions within a nucleus and is used to…
High-energy nuclear collisions create an energy density similar to that of the universe microseconds after the Big Bang, and in both cases, matter and antimatter are formed with comparable abundance. However, the relatively short-lived…
