Antiprotons match protons in response to strong nuclear force

Collider experiment finds antimatter behaves just like ordinary matter

PAIRING UP  Antiprotons are among the particles produced when gold nuclei collide inside a particle accelerator. For the first time, researchers at Brookhaven National Laboratory have measured the interaction between these antiprotons.
