DOWNLOAD EBOOKThe SEWM2002 workshop, like the ones before, brought together theoretical physicists working on thermal field theory and, more generally, on (resummation) techniques for deriving effective actions based on QCD and the electroweak standard model of elementary particle physics, but describing nonstandard situations. The focus was on the temperature/chemical potential phase diagram of QCD, considered both analytically and with lattice gauge theory, equilibrium and nonequilibrium thermo field theory, and on heavy ion physics. Other related topics were ?small x physics? in QCD, electroweak baryogenesis, inflation, and dark energy in the early universe.

DOWNLOAD EBOOKEffective models of strong and electroweak interactions are extensively applied in particle physics phenomenology, and in many instances can compete with large-scale numerical simulations of Standard Model physics. These contexts include but are not limited to providing indications for phase transitions and the nature of elementary excitations of strong and electroweak matter. A precondition for obtaining high-precision predictions is the application of some advanced functional techniques to the effective models, where the sensitivity of the results to the accurate choice of the input parameters is under control and the insensitivity to the actual choice of ultraviolet regulators is ensured. The credibility of such attempts ultimately requires a clean renormalization procedure and an error estimation due to a necessary truncation in the resummation procedure. In this concise primer we discuss systematically and in sufficient technical depth the features of a number of approximate methods, as applied to various effective models of chiral symmetry breaking in strong interactions and the BEH-mechanism of symmetry breaking in the electroweak theory. After introducing the basics of the functional integral formulation of quantum field theories and the derivation of different variants of the equations which determine the n-point functions, the text elaborates on the formulation of the optimized perturbation theory and the large-N expansion, as applied to the solution of these underlying equations in vacuum. The optimisation aspects of the 2PI approximation is discussed. Each of them is presented as a specific reorganisation of the weak coupling perturbation theory. The dimensional reduction of high temperature field theories is discussed from the same viewpoint. The renormalization program is described for each approach in detail and particular attention is paid to the appropriate interpretation of the notion of renormalization in the presence of the Landau singularity. Finally, results which emerge from the application of these techniques to the thermodynamics of strong and electroweak interactions are reviewed in detail.

DOWNLOAD EBOOKThis book, which presents a new view of quantum field theory, may serve as a research monograph and an alternative textbook examining topics which are not usually treated in conventional works. The first part contains a new nonperturbative regularization and probability interpretation, as well as a new treatment of effective dynamics for quantum fields based on algebraic representation theory in functional spaces. In the second part these methods are applied to selected topics in high energy physics. In a generalization of de Broglie's fusion theory, gauge bosons and fermions are considered as composites and the basic dynamics of the electro-weak sector of the standard model is derived as an effective theory from a regularized spinor fields model. Linear gravity is discussed in the same way. Audience: This volume will appeal to researchers concerned with the foundation of the theory of matter and forces including gravitation. It will also be of interest to those working with quantum field theoretic methods in various disciplines, such as particle physics, nuclear physics, condensed matter physics, and relativity.

DOWNLOAD EBOOKThis volume covers the collective behaviour of the Standard Model at finite temperature and density. The main physics motivation for this research comes from the early history of the Universe and also from the experimental efforts to create the quark-gluon plasma in laboratory experiments. Advances in theoretical investigations (effective theories, progress in numerical simulations, etc.) as well as the phenomenological applications figure in the broad spectrum of invited lectures. Prospective studies of beyond-the-Standard-Model theories receive particular attention. Non-equilibrium phenomena, especially questions related to baryon generation due to the electroweak anomaly and inflationary dynamics, are also discussed.

DOWNLOAD EBOOKAlready in 1997, the topics included in this meeting had been enlarged to include all different phases and phase transitions relevant on laboratory scales or in cosmology. The '98 meeting followed this trend, and there was a balanced combination of the physics associated with both strong and electroweak interactions (and beyond). The main motivation continues to be the understanding of the standard model in “extreme” situations, particularly relevant on the cosmological scale. Most contributions were in one way or another concerned with the finite-temperature aspects of strong and electroweak interactions, and, as in the previous meeting, one persistent theme was the present understanding of baryon-number asymmetry: how it can be created, and how it can be maintained beyond the earliest stages of the Universe. The recent progress in describing the real-time and nonequilibrium dynamics of the non-Abelian gauge was covered in a number of the main talks, as well as in several shorter contributions and posters. The conference presented examples of impressive analytical progress and equally impressive results from numerical simulations: the two techniques continue to fruitfully complement each other. One completely new theme at this conference was the recent suggestion that finite-density QCD may contain new and interesting condensed phases in the neighborhood of the conventional critical density separating quark matter from hadronic matter. All of these developments, and many more, are reflected in this book.

DOWNLOAD EBOOKThis volume presents an authoritative review of the physics of strongly and electroweakly interacting elementary particle matter in extreme conditions that prevailed in the very early Universe, and which are being recreated in high energy physics laboratories today. Exciting, high-quality experimental results from RHIC collider at Brookhaven, collected since summer 2000, suggest that strongly interacting quark-gluon plasma has indeed been produced. The study of these phenomena will form an important part of theoretical particle and nuclear physics for years to come.Based on the discussions of more than a hundred experts at the Strong and Electroweak Matter 2004 Meeting, this volume contains an up-to-date overview of present ideas on QCD matter: quark-gluon plasma in heavy ion collisions, phase structure, kinetics, thermalization and transport properties. Also discussed are topics related to the cosmology of the early Universe, dark matter, inflation and creation of particle-antiparticle asymmetries. Both analytic and numerical lattice Monte Carlo methods are emphasized.

DOWNLOAD EBOOKWith this thesis the author contributes to the development of a non-mainstream but long-standing approach to electroweak symmetry breaking based on an analogy with superconductivity. Electroweak symmetry breaking is assumed to be caused by dynamically generated masses of typical fermions, i.e., of quarks and leptons, which in turn assumes a new dynamics between quarks and leptons. Primarily it is designed to generate fermion masses and electroweak symmetry breaking is an automatic consequence. After the summary of the topic, the first main part of the thesis addresses the question as to whether the masses of known quarks and leptons provide sufficiently strong sources of electroweak symmetry breaking. It is demonstrated that neutrino masses subject to the seesaw mechanism are indispensable ingredients. The other two parts of the thesis are dedicated to the presentation of two particular models: The first model is based on the new strong Yukawa dynamics and serves as a platform for studying the ability to reproduce fermion masses. The second, more realistic model introduces a flavor gauge dynamics and its phenomenological consequences are studied. Even though, in the past, this type of models has already been of some interest, following the discovery of the Standard-Model-like Higgs particle, it is regaining its relevance.

DOWNLOAD EBOOKThis book contains articles by experts on the plasma phase of quantum chromodynamics, and the plasma phase of electroweak interactions. The former plasma phase is being tested at RHIC (Brookhaven), and has been tested at CERN. Both plasmas have played roles in the development of the Universe since the Big Bang. A third topic is that of the high density colour superconductive state of matter, which may be present in the core of neutron stars.
