22 junio 2015

A basic characteristic of elementary particles, spin is used daily in certain imaging techniques; yet, previous studies of the mechanics behind proton spin did not add up. An experiment at the Relativistic Heavy Ion Collider shows how the characteristics of an antiquark, a constituent of the proton, contribute to proton spin.
