Preliminary results of antiproton experiment may provide clues in search for dark matter

Last week, at the biennial ICHEP conference, the AMBER experiment presented results from its first data-taking period. Taken in 2023, these results show preliminary plots of the antiproton's production cross section—the probability that antiprotons are produced when a beam of protons interacts with a helium target. Knowing more about how antiprotons are produced will help improve the sensitivity of searches for dark matter.
