Abstract 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 implications on the fundamental question of the baryon asymmetry of the universe. It is therefore crucial to determine the amount of anti-matter which our own galaxy already produces through the spallation of high-energy protons on the interstellar gas… Expand

Antimatter cosmic rays
Abstract The dark matter puzzle is still one of the unsolved mysteries of astronomy. Most of the matter in the universe is not visible and its nature remains unresolved. A fraction of it could beExpand
Cosmic-ray antideuterons as a signature for neutralino annihilation in the galactic halo
Abstract Once the energy spectrum of the secondary component is well understood, measurements of the antiproton cosmic-ray flux at the Earth will be a powerful tool to indirectly probe for theExpand
Astrophysics of Galactic charged cosmic rays
A review is given of the main properties of the charged component of galactic cosmic rays, particles detected at Earth with an energy spanning from tens of MeV up to about 10^19 eV. After a shortExpand
Cosmic rays, antihelium, and an old navy spotlight
Cosmic-ray anti-deuterium and anti-helium have long been suggested as probes of dark matter, as their secondary astrophysical production was thought extremely scarce. But how does one actuallyExpand
Impact of cosmic-ray physics on dark matter indirect searches
The quest for the elusive dark matter (DM) that permeates the Universe (and in general the search for signatures of Physics beyond the Standard Model at astronomical scales) provides a uniqueExpand
New calculation of antiproton production by cosmic ray protons and nuclei
A dramatic increase in the accuracy and statistics of space-borne cosmic ray (CR) measurements has yielded several breakthroughs over the last several years. The most puzzling is the rise in theExpand
Antideuterons in cosmic rays: sources and discovery potential
Antibaryons are produced in our Galaxy in collisions of high energy cosmic rays with the interstellar medium and in old supernova remnants, and possibly, in exotic sources such as primordial blackExpand
Review of the theoretical and experimental status of dark matter identification with cosmic-ray antideuterons
Recent years have seen increased theoretical and experimental effort towards the first-ever detection of cosmic-ray antideuterons, in particular as an indirect signature of dark matter annihilationExpand
Searches for Cosmic Antimatter
We know from experimental high energy physics that whenever matter is created, an equal amount of antimatter is also created. However, we live in a large region of the universe where the antimatterExpand
Dark matter searches with cosmic antideuterons: status and perspectives
The search for antideuterons in cosmic rays has been proposed as a promising channel for dark matter indirect detection, especially for dark matter particles with a low or intermediate mass. With theExpand


Propagation of cosmic-ray nuclei in a diffusing galaxy with convective halo and thin matter disk
A diffusion model for cosmic-ray propagation in the galaxy that includes the effects of convection in the halo is presented. Calculations are made for 13 primary and secondary nuclei with rigiditiesExpand

A detailed study of the hydrostatic equilibrium of the gas-field system perpendicular to the galactic plane in the neighborhood of the Sun, assuming that the magnetic field is parallel to the plane,Expand
Cosmic-ray secondary antiprotons - A closer look
Following a suggestion of Webber that early calculations underestimated the intensity of secondary anti-protons, three aspects of the calculation have been systematically reexamined: theExpand
Deuterons from High-Energy Proton Bombardment of Matter
The results of a process of formation of high-energy deuterons from targets exposed to 25 to 30 Bev proton beams are evaluated. The formation mechanism involves the pairing of a neutron and protonExpand
