Non-perturbative methods and lattice QCD

International Workshop on Non-Perturbative Methods and Lattice QCD (2000 : Zhongshan University), Eric B. Gregory, Xiang-Qian Luo9810245955, 9789810245955, 9789812811370

Lattice field theory is the most reliable tool for investigating non-perturbative phenomena in particle physics. It has also become a cross-discipline, overlapping with other physical sciences and computer science. This book covers new developments in the area of algorithms, statistical physics, parallel computers and quantum computation, as well as recent advances concerning the standard model and beyond, the QCD vacuum, the glueball, hadron and quark masses, finite temperature and density, chiral fermions, SUSY, and heavy quark effective theory.
