In this review article, we discuss the current status and future prospects of perturbation
theory as a means of studying the equilibrium thermodynamic and near-equilibrium …

This report gives a detailed account of relativistic quantum field theory in the grand
canonical ensemble. Three approaches are discussed: traditional Euclidean Matsubara …

This text introduces the theoretical framework for describing the quark-gluon plasma, an
important new state of matter. The first part of the book is a self-contained introduction to …

We perform a thorough study of thermal leptogenesis adding finite temperature effects, RGE
corrections, scatterings involving gauge bosons and by properly avoiding overcounting on …

We present an up-to-date review of Big Bang Nucleosynthesis (BBN). We discuss the main
improvements which have been achieved in the past two decades on the overall theoretical …

Hydrodynamic transport coefficients may be evaluated from first principals in a weakly
coupled scalar field theory at an arbitrary temperature. In a theory with cubic and quartic …

The evaluation of hydrodynamic transport coefficients in relativistic field theory, and the
emergence of an effective kinetic theory description, is examined. Even in a weakly coupled …

This monograph presents recent developments in quantum field theory at finite temperature.
By using Lie groups, ideas from thermal theory are considered with concepts of symmetry …

We analyse in detail the standard primordial nucleosynthesis scenario. In particular, we
discuss the key theoretical issues which are involved in a detailed prediction of light nuclide …

In this paper, we extend the study of bremsstrahlung photon production in a quark-gluon
plasma to the cases of soft static photons (q= 0) and hard real photons. The general …
