Abstract
In this minireview article, the transverse momentum spectra of final-state particles produced in high-energy hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions described by the multisource thermal model at the quark or parton level are summarized. In the model, the participant or contributor quarks or partons are considered to contribute together to the transverse momentum distribution of final-state particles with different modes of contributions. The concrete mode of contribution is generally determined by the difference of azimuthal angles of contributor partons in their emissions.
Highlights
In high-energy hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions, abundant data measured in experiments reflect colorful mechanisms of particle production and system evolution [1–3]
As the strongly interacting partonic medium formed at the relativistic heavy ion collider (RHIC) and large hadron collider (LHC), quark-gluon plasma (QGP) was predicted by the quantum chromodynamics (QCD) theory which describes the strong interactions [49–53]
This minireview article will summarize the method for describing the transverse momentum spectra of final-state particles produced in high-energy collisions in the framework of multisource thermal model at the parton level
Summary
In high-energy hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions, abundant data measured in experiments reflect colorful mechanisms of particle production and system evolution [1–3]. It should be noted that in the multisource thermal model, the sources changed from fireballs to participant partons means that the smaller contributor units at the deeper level are used. This is an important progress or improvement in the viewpoint of the model. As the strongly interacting partonic medium formed at the RHIC and LHC, QGP was predicted by the quantum chromodynamics (QCD) theory which describes the strong interactions [49–53] This minireview article will summarize the method for describing the transverse momentum spectra of final-state particles produced in high-energy collisions in the framework of multisource thermal model at the parton level.
