Quantum chromodynamics on the lattice: an introductory presentation

Detailed Summary

Lattice QCD is a powerful computational approach used by physicists to study the strong force, one of the four fundamental forces of nature and the cornerstone of particle physics. In this book, the authors present a meticulously crafted introduction to the complexities of lattice QCD. Beginning with the theoretical foundations of QCD, the book transitions to the lattice formulation of gauge theories, which discretizes continuous spacetime into a finite lattice grid to enable numerical computations. This approach is vital in analyzing systems where analytical solutions are either impractical or unattainable.

The text bridges mathematical rigor with practical application, offering a comprehensive discussion of Monte Carlo simulations, the main computational tool used in lattice QCD studies. Readers will also encounter detailed explanations of fermion formulations, lattice artifacts, chiral symmetry, renormalization, and finite-temperature QCD. The book concludes with applications of lattice QCD to phenomenology, providing examples that connect theoretical predictions to experimental observations.

What sets this book apart is its ability to balance theoretical depth and pedagogical clarity. While the mathematical framework is sophisticated, the authors ensure that the material remains accessible, even to readers without prior expertise in advanced quantum field theories or computational physics.
