标题： Isospin Violation and Possible Signatures of Disoriented Chiral Condensates in Ultrarelativistic Heavy Ion Collisions

摘要： 如果在重离子碰撞中形成了非定向的介子凝聚（或其他相干介子态的来源），由于相干性，可能放大了电荷宇称破坏的动力学效应。 明确地展示了通过改变相干态的电荷宇称一个单位，可以将凝聚体中的$\pi^0$数量改变为总数的某个有限比例。 这种被放大的电荷宇称破坏效应的一个可能特征是，在许多事件中平均的中性低能$p_T$介子与总介子数的比值可能明显偏离 1/3。 如果形成多个相干介子区域，这种信号不会被消除。 显示英文摘要

摘要： 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 collison. It is shown explicitly that altering the isospin of the coherent state by order of one unit can change the number of $\pi^0$'s 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 $p_T$ pions averaged over many events may differ markedly from 1/3. Such a signal would not be washed out if multiple domains of coherent pions form.
