多个生产过程中的一阶相变信号

On the First Order Phase Transitions Signal in Multiple Production Processes

J. Manjavidze, A. Sissakian

摘要:

我们给出了对一级相变敏感的化学势参数:如果(相互作用的强子或/和QCD等离子体)介质是沸腾的,它必须随蒸发(产生)粒子(强子)的数目而减小;如果没有发生相变,它必须随蒸发粒子(强子)的数目而增大。本文的主要部分讨论了如何测量强子非弹性过程中的“化学势”的问题。我们对这个参数的定义是相当一般的,但假设强子多重数足够大。简单的透明的唯象格子气模型被认为是为了清楚起见。

英文摘要:

We offer the parameter, interpreted as the "chemical potential", which is sensitive to the first order phase transition: it must decrease with number of evaporating (produced) particles (hadrons) if the (interacting hadron or/and QCD plasma) medium is boiling and it increase if no phase transition occur. The main part of the paper is devoted to the question: how one can measure the "chemical potential" in the hadron inelastic processes. Our definition of this parameter is quite general but assumes that the hadron multiplicity is sufficiently large. The simple transparent phenomenological lattice gas model is considered for sake of clarity only.
