Light antinucleus yields are calculated in a multiphase transport model (AMPT) coupled with a dynamical coalescence model. The model is tuned to reproduce the transverse momentum and rapidity distributions of antiproton in pp collisions at √ s = 7.7 GeV to 7 TeV. By applying a widely used cosmic ray propagation model, the antinucleus fluxes near the earth are estimated over a broad range of kinetic energies. Our result on the antideuteron flux is consistent with the calculations in the…

Prospects of detecting dark matter through cosmic-ray antihelium with the antiproton constraints
Cosmic-ray (CR) antihelium is an important observable for dark matter (DM) indirect searches due to extremely low secondary backgrounds towards low energies. In a given DM model, the predicted CR
Production of light (anti)nuclei in pp collisions at $\sqrt{s}~=~5.02$ TeV
The study of the production of nuclei and antinuclei in pp collisions has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high-energy hadronic
Voyager 2 Measurements in the Outer Heliosphere of the Energy Spectra of Cosmic-Ray Nuclei from Less than 100 MeV Nucleon–1 to More than 1.0 GeV Nucleon–1
We have made a new analysis of cosmic-ray data from the CRS experiment on the Voyager 2 (V2) spacecraft. This analysis, which includes both penetrating and stopping particles in the HET telescope,
Cosmic-ray antinuclei as messengers of new physics: status and outlook for the new decade
A second dedicated Antideuteron Workshop was organized at UCLA in March 2019, bringing together a community of theorists and experimentalists to review the status of current observations of cosmic-ray antinuclei, the theoretical work towards understanding these signatures, and the potential of upcoming measurements to illuminate ongoing controversies.
Observation of the antimatter helium-4 nucleus
The observation of the antimatter helium-4 nucleus, the heaviest observed antinucleus to date, is reported, providing an indication of the production rate of even heavier antimatter nuclei and a benchmark for possible future observations of in cosmic radiation.
Measurement of the cosmic ray proton spectrum from 40 GeV to 100 TeV with the DAMPE satellite
The measurement of the cosmic ray proton fluxes with kinetic energies from 40 GeV to 100 TeV, with 2 1/2 years of data recorded by the DArk Matter Particle Explorer (DAMPE), suggests the existence of a new spectral feature of cosmic rays at energies lower than the so-called knee and sheds new light on the origin of Galactic cosmic rays.
Observation of an Antimatter Hypernucleus
The observation of antihypertritons—comprising an antiproton, an antineutron, and an antilambda hyperon—produced by colliding gold nuclei at high energy, have implications spanning nuclear and particle physics, astrophysics, and cosmology.
