Abstract
Quark-hadron phase transition study in hadron-nucleus interactions in self-affine scaling scenario
Highlights
Quantum chromodynamics predicts that in high energy interactions, a new matter state–quark-gluon plasma (QGP)– may be formed
The hadrons produced in such processes are expected to remember a part of the history of these interactions and are believed to be most informative about the collision dynamics, hadronization mechanism and may, in principle, carry some relic information about their parent state
Since the existence of the phase transition is associated with properties of the nontrivial quantum chromodynamics, the study of quark-hadron phase transition has been a hot point in both particle physics and nuclear physics for more than a decade
Summary
Quantum chromodynamics predicts that in high energy interactions, a new matter state–quark-gluon plasma (QGP)– may be formed. The newly produced hot system subsequently cools and undergoes a phase transition from the deconfined QGP to confined hadrons [1, 2]. Among the various methods the Levy stable law [3, 4] helps to provide a useful diagnostic tool to detect the existence of possible phase transition in hadronization process. This law is characterized by the Levy stability index μ .This parameter μ , characterizing the width of probability distribution in the elementary partition of random cascade, takes value in the range [0,2] according to the requirement of Levy stability [3, 4]. On the other hand, when μ >1, there is a non-thermal phase transition during the cascading process
