Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...

At its start, the universe was a superhot melting pot that very briefly served up a particle soup resembling a "perfect," frictionless fluid. Scientists have recreated this "soup," known as ...

The United States' military has announced it is seeking to create powerful subatomic particle beams that would enable personnel to "see" through walls tens of yards thick and even peer deep ...

A portrait of nucleon-antinucleon bound state. Credit: Physical Review Letters (2024). DOI: 10.1103/PhysRevLett.132.151901 The proximity in mass to 2m p is suggestive of nucleon-antinucleon bound ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...
