Isospin violation and possible signatures of disoriented chiral condensates in ultrarelativistic heavy ion collisions

It is possible that isospin violating dynamical effects are amplified due to coherence if a disoriented chiral condensate (or other source of a coherent pion state) is formed in a heavy ion collision. It is shown explicitly that altering the isospin of the coherent state by order of one unit can change the number of π0ʹs in the condensate by some finite fraction of the total number. A possible signature of such amplified isospin violating effects is that the ratio of neutral to total low pT pions averaged over many events may differ markedly from 13. Such a signal would not be washed out if multiple domains of coherent pions form.
