Physicists from the STAR Collaboration have reported the first observation of a global spin alignment signal in heavy-ion collisions. Published in Nature on Jan. 18, the study provides a potential new avenue for understanding the strong interaction at work at the sub-nucleon level.

Data Reveal a Surprising Preference in Particle Spin Alignment
Given the choice of three different “spin” orientations, certain particles emerging from collisions at the Relativistic Heavy Ion Collider (RHIC), an atom smasher at Brookhaven National Laboratory, appear to have a preference. Recent results reveal a preference in global spin alignment of particles called phi mesons.
