Taken in 2023, these results show preliminary plots of the antiproton's production cross section—the probability that antiprotons are produced when a beam of protons interacts with a helium target.
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 ...
Subatomic particles of the same mass as a proton but having a negative electric charge and oppositely directed magnetic moment, antiprotons are the antiparticles of protons. Even though they are ...
These antiprotons are produced by colliding particles together in Cern's accelerators. They arrive at the antimatter lab along pipes at speeds that are close to the speed of light. This is much ...
Because WIMPs are very heavy, it is possible that these annihilations create antinuclei – the antimatter version of nuclei comprising antiprotons and antineutrons. Some of these antinuclei could make ...
Scientists and journalists share a core belief in questioning, observing and verifying to reach the truth. Science News reports on crucial research and discovery across science disciplines. We ...
