This book was released on 2010-03-24 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an introduction to main ideas used in the physics of ultra-relativistic heavy-ion collisions. The links between basic theoretical concepts (discussed gradually from the elementary to more advanced level) and the results of experiments are outlined, so that experimentalists may learn more about the foundations of the models used by them to fit and interpret the data, while theoreticians may learn more about how different theoretical ideas are used in practical applications. The main task of the book is to collect the available information and establish a uniform picture of ultra-relativistic heavy-ion collisions. The properties of hot and dense matter implied by this picture are discussed comprehensively. In particular, the issues concerning the formation of the quark-gluon plasma in present and future heavy-ion experiments are addressed.

Book excerpt: This thesis focuses on developing a standard theoretical framework to study the bulk dynamics and electromagnetic probes of ultra-relativistic heavy-ion collisions, which are presently studied experimentally at the Relativistic Heavy-Ion Collider (RHIC) and the Large Hadron Collider (LHC). We developed a modular numerical package with different (exchangeable) modular describing different evolution stages of the expanding fireball created in these collisions. For each stage of the collisions, we will give a detailed description of the theoretical model and its corresponding numerical implementation, supplemented with code checking tests.

This book was released on 1990 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: We introduce the coalescence variables, a set of three boost-invariant kinematic quantities which may be used in analyzing n-particle correlations. These variables characterize the invariant mass of an n-particle and in three directions and separate the timelike and spacelike characteristics of the source. The analytic Kolehmanien-Gyulassy model is generalized to give two, three, and four-particle correlation functions, with coherence and Coulomb corrections applied to the basic formalism. We demonstrate the relation of the coalescence variables to be radius and duration of the source, and find that for sufficiently large transverse radii, Coulomb effects can suppress the structure of the Hanbury-Brown-Twiss correlations so that no significant information on source size can be obtained. 11 refs., 10 figs.

Available in PDF, EPUB and Kindle. Book excerpt: The Multi Module Model for Ultra-Relativistic Heavy Ion Collisioiis at RHIC and LHC energies is presented. It uses the Effective String Rope Model for the calculation of the initial stages of the reaction; the output of this model is used as the initial state for the subsequent one-fluid calculations. It is shown that such an initial state leads to the creation of the third flow component. The hydrodynainical evolution of the energy density distribution is also presented.

Strings are formed due to color exchange between quarks at each individual nucleon nucleon collision. The fragmentation is treated as in ee− or lepton nucleon scattering. Calculation for pp, pA, and AA were carried out using the Monte Carlo code VENUS for Very Energetic Nuclear Scattering (version 1.0). 20 refs., 6 figs.

Download or read book Relativistic Heavy Ion Physics In 2 Volumes written by Laszlo P Csernai and published by World Scientific. This book was released on 1991-04-22 with total page 749 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an overview of relativistic heavy ion physics with particular emphasis on those theoretical approaches which seek an understanding and explanation of the measurements. These approaches try to build a bridge between more basic theories, such as lattice QCD or nucleon-nucleon interactions, and complicated experimental observables involving a large number of particles. Thus, mainly theoretical approaches are discussed here which are strongly and directly related to experiments, and in turn they are phenomenological to some extent. These models use the available information from more complete reaction model describing the whole collision and the observables.It is suitable as a text for advanced undergraduate and graduate students - both experimentalists and theorists - for studies in the field of relativistic heavy ion physics. It may also serve as a handbook where basic concepts of reaction models can be found and the most important references for further reading are provided.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last century, matter was confirmed to be made up from molecules which consist of two atoms or more. The atom itself consists of a nucleus made of protons and neutrons, and electrons "circling'' around the nucleus. The number of electrons or protons distinguish different elements. Later on, protons and neutrons were found not to be elementary particles but rather composite particles. The question turned then to be what are protons and neutrons made of and this is the focus of elementary particle physics. According to the standard model, protons and neutrons are made up of quarks and gluons. The theory that describes quarks and gluons is called quantum chromodynamics (QCD). According to this theory, quarks and gluons can not be detected freely; they appear only inside hadrons but are never observed freely (confinement). However, at high temperatures and/or densities a transition may happen where quarks and gluons do not exist in bound states (hadrons) anymore but rather exist freely (the asymptotic freedom). This phase of the nuclear matter is known as the quark-gluon plasma (QGP).To learn more about the QCD phase diagram, mainly the confinement and de-confinement transition, many different experiments have been performed from fixed target experiments to high-energy heavy-ion collisions in almost three decades. The discovery of QGP came from ultrarelativistic heavy-ion collision (URHIC) experiments. By ultrarelativistic heavy-ion collisions, we mean heavy ions like gold or lead that have been accelerated to speeds which are close to the speed of light (the ion momentum is much larger than its rest mass). Nowadays, ultrarelativistic heavy-ion collision experiments at the Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) are being used to create and study the quark-gluon plasma. From the early days after confirming the existence of the QGP, relativistic hydrodynamics has been used to describe the hadron spectra and collective flow seen in these experiments and has been quite successful. Since then, different approaches have been developed to model the physics of the QGP. The first approach used was ideal hydrodynamics where the QGP is assumed to behave like a perfect fluid with no viscosity. However, improvements in both the experimental and theoretical sides demonstrated the importance of including dissipative (viscous) effects in QGP modeling. The resulting relativistic viscous hydrodynamics models have been quite successful in describing the data. Despite this success, studies found that the QGP generated in URHICs is a highly momentum-space anisotropic plasma which means that viscous hydrodynamics will break down in some situations. To take this into account, anisotropic hydrodynamics (aHydro) was developed. In aHydro, one includes the momentum-space anisotropies in the distribution function at leading-order, whereas viscous hydrodynamics is expanded around the isotropic distribution function as the leading term and the viscous effects are included as correction terms. In this study, we present a new method for imposing a realistic equation of state in anisotropic hydrodynamics which is called quasiparticle anisotropic hydrodynamics (aHydroQP). In this method, we introduce a single finite-temperature quasiparticle mass which is fit to QCD lattice data. By taking moments of the Boltzmann equation assuming an anisotropic distribution function, we obtain a set of coupled partial differential equations which can be used to describe the 3+1d spacetime evolution of the QGP. Due to the numerical difficulties and the need to understand this new method more, instead of considering the 3+1d case immediately, we begin by studying two simpler cases. First, we specialize to the case of a 0+1d system undergoing boost-invariant Bjorken expansion and compare with the standard method of imposing the equation of state in anisotropic hydrodynamics (aHydro). We find practically no differences between the two methods results for the temperature evolution and the scaled energy density. When we compare the pressure anisotropy, we see only small differences, however, we find significant differences in the evolution of the bulk pressure correction. Second, we present the results in azimuthally-symmetric boost-invariant (1+1d) systems and compare the quasiparticle model with the standard aHydro model and second order viscous hydrodynamics. We compare the three methods' predictions for the primordial particle spectra, total number of charged particles, and average transverse momentum for various values of the shear viscosity to entropy density ratio. We show that they agree well for small shear viscosity to entropy density ratio, but show clear differences at large values of shear viscosity to entropy density ratio. Third, and most importantly, we present the phenomenological predictions of 3+1d quasiparticle anisotropic hydrodynamics compared with LHC 2.76 TeV Pb-Pb collisions. We present comparisons of charged-hadron multiplicity, identified-particle spectra, identified-particle average transverse momentum, charged-particle elliptic flow, identified-particle elliptic flow, elliptic flow as a function of pseudorapidity, and HBT radii. We find good agreement when compared with ALICE data. Looking to the future, we plan to include next-leading-order anisotropic hydrodynamics corrections by including the off-diagonal terms of the anisotropy tensor in quasiparticle anisotropic hydrodynamics. However, since this will be very hard and numerically intense, we consider first next-leading-order anisotropic hydrodynamics using the standard method for imposing the equation of state. To do so, we Taylor-expand assuming small off-diagonal terms to make the formalism easier and numerically tractable. Then, by taking moments of the Boltzmann equation, we find the dynamical equations needed to model the full 3+1d system. In this part of the work, we present only the theory setup and leave the numerical analysis for a future work.
