Experiment hints at new mesic nuclei, probing how matter gains mass
Physicists working at Germany’s GSI Helmholtz Centre have found the first experimental hints that an unusually heavy subatomic particle, the eta-prime meson, can bind to an atomic nucleus. If ...
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 ...
In 2023, scientists detected a subatomic particle called a neutrino hitting Earth with an energy level so extreme it seemed impossible. No known ...
Over a century ago, Ernest Rutherford discovered the proton by splitting the atom in a laboratory in Manchester. Today, researchers based in Manchester have discovered a new particle that Rutherford ...
