Making analogy with the " " spin-glass " phase in polymers, peschanski put forward the idea that there exists non-thermal phase transition in multiparticle systems . a parameter xq has been introduced to characterize the non-thermal phase transition 通過(guò)類(lèi)比聚合體中的“自旋玻璃相”,peschanski提出隨機(jī)級(jí)聯(lián)的多粒子產(chǎn)生過(guò)程中存在非熱相變,并提出表征相變的特征參數(shù)_q的公式。
In the second part of the thesis, the non-thermal phase transition in high energy collisions is studied in detail in the framework of random cascade model . the relation between the characteristic parameter xq of phase transition and the rank q of moment is obtained using monte carlo simulation, and the existence of two phases in self-similar cascading multiparticle systems is shown . the relation between the critical point qc of phase transition on the fluctuation parameter q is obtained and compared with the experimental results from na22 文章第二部分中,我們用隨機(jī)級(jí)聯(lián)模型對(duì)高能碰撞中的非熱相變作了仔細(xì)研究,用montecarlo模擬得到了表征相變的特征參數(shù)_q與矩階數(shù)q之間的關(guān)系,證實(shí)了自相似多粒子系統(tǒng)中存在兩相,求出了相變點(diǎn)q=q_c對(duì)起伏參數(shù)的依賴(lài)關(guān)系,并和na22實(shí)驗(yàn)結(jié)果進(jìn)行了比較。
