Researchers have shown that in polarized proton-proton collisions, the neutral pions in the very forward area of collisions — where direct interactions involving quarks and gluons are not applicable — still have a large degree of left-right asymmetry. This finding suggests that the previous consensus regarding the generation of particle in such collisions need to be reevaluated.
