Indirect Detection of Neutralino Dark Matter
Dark matter detection experiments are getting ever closer to the sensitivity needed to detect the primary particle physics candidates for nonbaryonic dark matter. Indirect detection methods include searching for antimatter and gamma rays, in particular gamma ray lines, in cosmic rays and high-energy neutrinos from the centre of the Earth or Sun caused by accretion and annihilation of dark matte...
متن کاملPrimordial Antimatter in the Contemporary Universe
In some baryogenesis scenarios, the universe acquires a non-vanishing average baryonic charge, but the baryon to photon ratio is not spatially constant and can be even negative in some space regions. This allows for existence of lumps of antimatter in our neighborhood and the possibility that very compact antimatter objects make a part of cosmological dark matter. Here I discuss the peculiar si...
متن کاملAntimatter Research in Space
Two of the most compelling issues facing astrophysics and cosmology today are to understand the nature of the dark matter that pervades the universe and to understand the apparent absence of cosmological antimatter. For both issues, sensitive measurements of cosmic-ray antiprotons and positrons, in a wide energy range, are crucial. Many different mechanisms can contribute to antiprotons and pos...
متن کاملThe Alpha Magnetic Spectrometer (AMS): search for antimatter and dark matter on the International Space Station
The disappearance of cosmological antimatter and the pervasive presence of dark matter are two of the greatest puzzles in the current understanding of the universe. The Big Bang model assumes that, at its very beginning, half of the universe was made out of antimatter. The validity of this model is based on three key experimental observations: the recession of galaxies (Hubble expansion), the h...
متن کاملThe Gravitational Segregation of Matter and Antimatter
If matter and antimatter appeared in equal amounts at the creation of the universe, where is the antimatter? I offer a new hypothesis for the segregation of matter and antimatter based on the assumptions that matter has positive mass, antimatter has negative mass, and that the gravitational mass is equal to the inertial mass. This hypothesis, based on CPM (chargeparity-mass) symmetry, predicts ...
