On a similar note, many dark-matter candidates are predicted to produce more cosmic-ray antiprotons than are observed if the annihilation rate is normalized to the electron and positron signals ...

Positrons are the antimatter equivalents of electrons. Similar to antiproton-nucleon annihilation, positron-electron annihilation is also stable and yields a significant amount of energy.

Positron Annihilation Spectroscopy (PAS ... This research highlights the importance of accurately modeling the electron-positron correlations to improve the understanding of defect characteristics ...

g-factor engineering of an electron spin and rapid annihilation of a hole will be key issues. This project will contribute to the realization of a quantum repeater needed for unconditionally secure ...
