Book Description
The purpose of this book is to give a systematic pedagogical exposition of the quantitative analysis of Wilson lines and gauge-invariant correlation functions in quantum chromodynamics. Using techniques from the previous volume (Wilson Lines in Quantum Field Theory, 2014), an ab initio methodology is developed and practical tools for its implementation are presented. Emphasis is put on the implications of gauge invariance and path-dependence properties of transverse-momentum dependent parton density functions. The latter are associated with the QCD factorization approach to semi-inclusive hadronic processes, studied at currently operating and planned experimental facilities. Contents: Introduction Particle Number Operators in Quantum Mechanics and in Quantum Field Theory Geometry of Quantum Field Theories Basics of Wilson Lines in QCD Gauge-Invariant Parton Densities Simplifying Wilson Line Calculations Brief Literature Guide Conventions and Reference Formulae Integrations Bibliography Index

Book Description
The Large Hadron Collider at CERN is currently the most powerful particle collider. It collides protons at the center of mass energy of 13 TeV. At such high energies parton densities in both protons are extremely high. This leads to the enhanced probability for multi-parton interactions. These are events in which more than one partonic interaction occurs per one nucleon collision. The multi-parton interactions, which are characterized by a hard scale, can be described in QCD by means of double parton distributions. In this thesis we propose a construction of the double unintegrated parton distribution functions which, in addition to the longitudinal momentum fractions, include the dependence on the transverse momenta of partons. To this aim, we extend the formalism that was used previously for the single unintegrated parton distribution functions. Starting from the homogeneous part of the equation for the integrated double parton distribution function, we construct the double unintegrated parton distribution functions which are the convolutions of the integrated parton densities and the Sudakov form factor. We present first numerical studies of these distributions. In particular, double unintegrated parton density functions are studied as a function of the transverse momenta for fixed scales and fixed values of the longitudinal momentum fractions. We also discuss the numerical methods used for the calculation of these double unintegrated parton distribution functions.

Book Description
This volume describes the Pomeron, an object of crucial importance in very high energy particle physics. The book starts with a general description of the Pomeron within the framework of Regge theory. The emergence of the Pomeron within scalar field theory is discussed next, providing a natural foundation on which to develop the more realistic case of QCD. The reggeization of the gluon is demonstrated and used to build the Pomeron of perturbative QCD. The dynamical nature of the Pomeron is then investigated. The role of the Pomeron in small-x deep inelastic scattering and in diffractive scattering is also examined in detail. The volume concludes with a study of the colour dipole approach to high energy scattering and the explicit role of unitarity corrections. This book will be of interest to theoretical and experimental particle physicists, and applied mathematicians.

Book Description
This is a self-contained introduction to perturbative and nonperturbative quantum chromodynamics. Relativistic quantum field theory is recapitulated and scattering theory is discussed in the framework of scalar quantum electrodynamics. Then the gauge theory of quarks and gluons is introduced, before moving on to an advanced discussion of perturbative and nonperturbative techniques in state-of-the-art QCD.

Book Description
Many facets of quantum chromodynamics (QCD) are relevant to the in-depth discussion of theoretical and experimental aspects of high-energy nucleus-nucleus collisions. Exciting phenomena are being discovered in such ultrarelativistic heavy ion collisions, notably the increasingly important role of deconfined quark-gluon matter created in the early stage. The book contains lectures on the physics of hot dense matter, the expected phase transitions and colour superconductivity, recent developments in the treatment of nonlinear effects at large parton densities, fundamental issues in the phenomenology of ultrarelativistic heavy collisions. The latest data on heavy ion collisions are also presented. A unique collection of lectures on the many facets of QCD relevant to the physics of hot dense matter.
