We propose a unified space-time picture of baryon stopping and quark-gluon plasma creation in ultrarelativistic heavy-ion collisions. It is assumed that the highly Lorentz contracted nuclei are decelerated by the coherent color field which is formed between them after they pass through each other. This process continues until the field is neutralized by the Schwinger mechanism. Conservation of energy and momentum allow us to calculate the energy losses of the nuclear slabs and the initial energy density of the quark-gluon plasma.
我们提出了一个关于超高能重离子碰撞中重子阻止和夸克-胶子等离子体产生的统一时空图像。假定高度洛伦兹收缩的原子核在相互穿过之后，通过它们之间形成的相干色场而减速。这个过程一直持续到该场通过施温格机制被中和。能量和动量守恒使我们能够计算核平板的能量损失以及夸克-胶子等离子体的初始能量密度。
