标题： Strange Particle Production from Quark Matter Droplets

摘要： 我们最近引入了新的方法来研究超相对论核散射，通过将弦模型方法与热描述联系起来。 弦模型用于提供关于能量密度涨落的信息。 高能量密度区域被视为夸克物质液滴，并进行宏观处理。 在SPS能量下，我们主要发现中等大小的液滴——能量高达几十GeV。 一个关键问题是单个夸克物质液滴的微正则处理。 每个液滴根据可用的n体相空间立即发生强子化。 由于可能的强子配置数量巨大，已开发了特殊的蒙特卡罗技术来计算这种分解。 我们展示了关于此类强子化产生奇异粒子的结果，以及与弦衰变的比较。 显示英文摘要

摘要： We recently introduced new methods to study ultrarelativistic nuclear scattering by providing a link between the string model approach and a thermal description. The string model is used to provide information about fluctuations in energy density. Regions of high energy density are considered to be quark matter droplets and treated macroscopically. At SPS energies, we find mainly medium size droplets --- with energies up to few tens of GeV. A key issue is the microcanonical treatment of individual quark matter droplets. Each droplet hadronizes instantaneously according to the available n-body phase space. Due to the huge number of possible hadron configurations, special Monte Carlo techniques have been developed to calculate this disintegration. We present results concerning the production of strange particles from such a hadronization as compared to string decay.
