我们提出了一个可能的缩放解决方案，预平衡的演变，插值之间的不稳定性存在于稠密胶子系统产生后，立即重离子碰撞和最终的平衡发生后。我们的解取决于一个参数δ。根据δ的值，我们提出的解决方案在自底向上给出的进化的中间阶段或接近尾声时与自底向上的图片相匹配。我们详细讨论了为什么我们相信我们的解决方案是自洽的，我们也指出了为什么它是难以实际证明的一致性。
We present a possible scaling solution to preequilibrium evolution which interpolates between the instability present in the dense gluon system produced immediately after a heavy ion collision and the final equilibration which occurs later. Our solution depends on a single parameter δ. Depending on the value of δ, our proposed solution matches onto the bottom-up picture either at an intermediate stage or toward the end of the evolution given by bottom-up. We discuss in detail the reasons why we believe our solution is self-consistent, and we also point out why it is difficult to actually prove consistency.
