book. In relativistic nucleus–nucleus (A–A) collisions, the notions of participant and spectator nucleons are useful geometrical concepts to study the nuclear reaction mechanisms. After the collision, the overlapping parts of the two colliding nuclei are considered as participants, which disintegrate.

As the bombarding energy in nucleus-nucleus collision increases the structure aspects of the nuclei become less relevant. Except for the bulk properties of the nuclei (size and number of nucleons), the physics involved is primarily due to the individual, and sometimes collective, hadronic collisions.

The first and foremost issue at hand concerning the nucleus—nucleus collision relates to the internal Strangeness in relativistic heavy ion collisions strange quark production, namely the pair production process gg—3 s~,is, in principle, the same for multiply strange antibaryons when the plasma state fragments and recombines to.

Quarkonium suppression in nucleus-nucleus collisions is a powerful tool to probe the density and temperature of the medium created in heavy ion collisions.

Forward rapidity measurements in p (d)+Au collisions are essential to understand how quarkonium states are affected by initial state effects, formation time, and local particle multiplicity.

The production of jets, and high-p T leading pions from jets, in d-Au collisions at the Relativistic Heavy-Ion Collider (RHIC) and p-Pb collisions at the Large Hadron Collider (LHC) are a modified version of the event generator PYTHIA, in conjunction with a nuclear Glauber Monte-Carlo event generator, we demonstrate how events with a hard jet may be simulated, in such a way that.

With increasing collision energy, nuclear matter is probed at finer and finer resolution and several facets of nuclear matter are revealed. A nucleus–nucleus collision at relativistic energy passes through different stages, and there are several models in vogue for relativistic heavy ion collisions.

In practice, the simulations were conducted using PHITS incorporated with SMM, as illustrated in Fig. JQMD is an event generator for the non-equilibrium phase of nucleus–nucleus interactions, that simulates the time-evolution of nucleons during intra-nuclear cascade on the basis of effective interaction and two-body collisions.

In heavy-ion collisions at relativistic high energy, a large amount of energy is deposited involved in a nucleus–nucleus collision. Therefore, the investigation of these charged low-energy, multiply charged fragments and are mainly evaporated particles from the tar-get nuclei.

Grey particles have a range greater than 3 mm and.

By the end of this century, a new regime of very high energy density matter will be accessible in nucleus-nucleus collisions at the new colliders RHIC (Relativistic Heavy-Ion Collider) at BNL and. projectile fragments especially in the case of projectile helium fragments (with charge Z = 2) emanated from the nucleus–nucleus collisions.

The main motive of this paper is to analyse the disintegration of relativistic 28Si nuclei with different target nuclei of varying sizes present in. nucleus–nucleus collisions at relativistic high energies, has been observed experimentally for a variety of collision processes such as hadron–hadron,6,7) These are low energy, multiply charged fragments and are mainly evaporated particles from the target nuclei.

Grey particles have a range greater than 3mm and ionization g min. Two and three particle short-range correlations among the target evaporated fragments as well as among the target recoil protons produced in 12 A GeV 4 He- A GeV 16 O- 60 A GeV 16 O- A GeV 84 Kr- and A GeV Au-AgBr interactions are investigated in emission angle space and azimuthal angle space respectively.

Analysis of target-fragmented "black" particles in nuclear emulsion from high-energy relativistic interactions initiated by 28 Si at A GeV/c is investigated. The number of slowly emitted particles from the struck target nucleus is considered as a measure of the degree of excitation of the residual nucleus.

Which is the result desired. Decay problems can be solved in a similar manner; that is, by conserving energy and momentum. The situation in which a particle of mass M and energy E decays into two identical particles is also shown in.

As shown, one particle heads off in the y-direction, and the other at an angle problem is to calculate the energies of these particles resulting from the. produced in relativistic nuclear collisions is still important and relevant for parameter.

As in collisions of hadrons with nucleons and nuclei, a large part of the total cross–section for nucleus–nucleus interactions at high energies is due to multiple productions of particles.

multiply charged fragments based on the following. Nuclear fragmentation is an important experimental phenomenon in nucleus-nucleus collisions at relativistic high energy (Jilany, ; Andronic et al., ). Large numbers of models (Joseph et al.

Zhiming Li, and Jin Wu./JPSCP. projectile helium fragments are part of these nuclear systems. As these relativistic projectile helium fragments are the major part of the projectile fragments and also they carry the rapidity of the projectile beam so they can provide us the necessary information about the fragmentation mechanism of heavy ion nucleus–nucleus collisions.

There. The experimental results of space, azimuthal, and projected angular distributions of target black fragments produced in silicon-emulsion collisions at A GeV/c (the Dubna energy) are reported.

A multi-source ideal gas model is suggested to describe the experimental angular distributions.

The experimental results of multiplicity distributions of grey and relativistic shower particles emitted in the interactions of 28Si and 12C ions at A GeV/c with nuclear emulsion are reported. This is a list of past and current experiments at the CERN Super Proton Synchrotron (SPS) facility since its commissioning in [1] The SPS was used as the main particle collider for many experiments, and has been adapted to various purpose ever since its inception.

use of heavy nuclei as targets in relativistic particle collisions enables the scientists to study the hadronic production mechanism. Thus, during the last three decades the production of backward particles in hadron–nucleus and nucleus-nucleus interactions at relativistic.

According to the participant-spectator model[1], projectile fragments, target fragments and produced particles, three different types of secondary particles are produced in high energy nucleus-nucleus collisions.

In the present articles an attempt has been made for the determination of multiplicity fluctuations of the secondary charged particles produced in relativistic heavy ion collisions with the help of the Ginzburg-Landau (G-L) approach to find the first-order phase transition (QGP to hadron phase state).
