In Sections 4, 5, and 6 we will describe in detail the current status for positron, antiproton
and antinuclei indirect searches: our purpose is to provide a case-by-case discussion mostly focused on the relevance of CR transport physics in antimatter channels for DM indirect detection.
According to Andreas Mooser, second author of the study and member of RIKEN FSL, "Looking forward, using this technique, we will be able to make similarly precise measurements of the antiproton
at the BASE experiment in CERN, and this will allow us to look for further hints for why there is no antimatter in the universe today."
The single-particle detectors used in the measurements were partly developed by the Riken researchers, some of whom had previously worked on similar traps at CERN's Antiproton
Among the topics are the 600 MeV synchrocyclotron: laying the foundation, the intersecting storage rings: the first hadron collider, the CERN antiproton
program: imagination and audacity rewarded, the large hadron collider: the energy frontier, knowledge and technology: sharing with society, and managing the laboratory and large projects.
This new research, undertaken by the ALPHA experiment at CERN's Antiproton
Decelerator (AD) in Geneva, is the first time that the electric charge of an anti-atom has been measured to high precision.
It is known indeed that proton and antiproton
virtual couples are formed by vacuum fluctuations and high order two-photon interactions during photon fluctuations able to generate fermion-antifermion pairs .
The 1.6 billion [euro] international project, known as the Facility for Antiproton
and Ion Research (Fair), will help scientists to better understand the universe, and promises to become for nuclear physics what Cern is to particle physics.
A hydrogen atom consists of a proton and an electron, and its antimatter counterpart, antihydrogen, consists of a positron and an antiproton
, both with the opposite charge of the electron and proton respectively.
Antihydrogen is made of an antiproton
and a positron.
An antihydrogen atom is made from a negatively charged antiproton
and a positively charged positron, the antimatter counterpart of the electron.
A normal, positively charged proton, for instance, finds its antimatter counterpart in a negatively charged antiproton
. Similarly, the normal, negatively charged electron's antimatter counterpart is the positron.
