“…For each hadron-muon pair, the invariant mass of a possible muonic atom can be reconstructed using the daughter momenta and masses. The following quantity has been studied [295] oration has shown [295] such peaks for pµ − , pµ + , K − µ + , and K + µ − pairs, providing evidence for the existence of muonic atoms with these configurations.…”

Antinuclei in heavy-ion collisions

We review progress in the study of antinuclei, starting from Dirac's equation and the discovery of the positron in cosmic-ray events. The development of proton accelerators led to the discovery of antiprotons, followed by the first antideuterons, demonstrating that antinucleons bind into antinuclei. With the development of heavy-ion programs at the Brookhaven AGS and CERN SPS, it was demonstrated that central collisions of heavy nuclei offer a fertile ground for research and discoveries in the area of antinuclei. In this review, we emphasize recent observations at Brookhaven's Relativistic Heavy Ion Collider and at CERN's Large Hadron Collider, namely, the antihypertriton and the antihelium-4, as well as measurements of the mass difference between light nuclei and antinuclei, and the interaction between antiprotons. Physics implications of the new observations and different production mechanisms are discussed. We also consider implications for related fields, such as hypernuclear physics and spacebased cosmic-ray experiments.

“…The STAR collaboration has calculated [295] the C + /C − ratio for both Kµ and Kπ systems. The ratio for Kµ is indeed close to unity, while the ratio for the Kπ system, which is not expected to form in heavy-ion collisions and serves as a consistency check, deviates from unity.…”
