Larger Domains of Disoriented Chiral Condensate Through Annealing

Abstract

Relativistic heavy ion collisions can generate metastable domains in which the chiral condensate is disoriented. Nucleus-sized domains can yield measurable fluctuations in the number of neutral and charged pions. We propose a scenario in which domains are `annealed' by a dynamically evolving effective potential in the heavy ion system. Domains of sizes exceeding 3~fm are possible in this scenario.
