高能碰撞中的Hawking-Unruh强子化和奇异产生

Hawking-Unruh hadronization and strangeness production in high energy collisions

P. Castorina, H. Satz

摘要:

夸克($q$)-反夸克($\bar q$)对的产生和连续的弦破裂作为隧穿穿过色禁闭事件视界的解释导致了一个热强子谱,该谱具有与夸克加速度$a$相关的普适Unruh温度$T \simeq 165$ Mev,由$T=a/2π$。由此产生的温度取决于夸克质量,然后取决于产生的强子的含量,导致偏离完全平衡,从而抑制了基本碰撞中奇异粒子的产生。在夸克密度大得多的核-核碰撞中,必须引入平均温度(加速度),这会稀释夸克质量效应,奇异抑制几乎消失。

英文摘要:

The interpretation of quark ($q$)- antiquark ($\bar q$) pairs production and the sequential string breaking as tunneling through the event horizon of colour confinement leads to a thermal hadronic spectrum with a universal Unruh temperature, $T \simeq 165$ Mev,related to the quark acceleration, $a$, by $T=a/2π$. The resulting temperature depends on the quark mass and then on the content of the produced hadrons, causing a deviation from full equilibrium and hence a suppression of strange particle production in elementary collisions. In nucleus-nucleus collisions, where the quark density is much bigger, one has to introduce an average temperature (acceleration) which dilutes the quark mass effect and the strangeness suppression almost disappears.
