February 29, 2016
A new measurement by RHIC's STAR collaboration reveals that the force between antiprotons (p with bar above) is attractive and strong - just like the force that holds ordinary protons together within the nuclei of atoms.
First Measurement of the Force that Makes Antimatter Stick Together
Antimatter nuclei as large as antihelium-4—containing two antiprotons and two antineutrons—have been observed in heavy-ion collisions
