kaon pairs emerging from heavy ion collision at STAR

Caption

Tracking pairs of positively and negatively charged kaons (K+, K-)—the decay products of phi mesons (Φ)—revealed that these mesons appear to have a preference for one among three possible spin states. A new theoretical model suggests that local fluctuations in the strong nuclear force may explain this preference.
