SPS能区200GeV下非对称碰撞末态强子的快度分布
Study of Rapidity Distributions of the Charged-hadrons at 200 GeV per Nucleon at SPS
摘要
Abstract
We make quantitative description for the rapidity of charged-hadron multiplicity in proton-, deuteron-, oxygen- and sulphur-nucleus collisions at 200 GeV per nucleon by using the thermalization component model (TCM). It is found that the total multiplicity distribution is the sum of the contributions from the target fragmentation region, the projectile fragmentation region, and the central rapidity region. It is realized that the collective flow has been formed and the thermalization has been reached at the central rapidity region. And then, charged particle (net protons-p-p), negatively charged hadrons- h-) distributions ions are studied, which can help us to understand the transport mechanism of valence quarks.关键词
