(Théorie des Interactions Fondamentales) Addressing Quantum Chromodynamics (QCD) in the infrared is a notoriously difficult task due to the size of the interaction strength. This has instigated the development of non-perturbative approaches based either on the lattice discretization and the statistical evaluation of the QCD functional integral, or on its continuum reformulation in terms of infinite hierarchies of equations. Lattice QCD provides an almost exact description of QCD that can however not be used in all situations. As for continuum approaches, even though they can be extended to these situations in principle, they very often rely on uncontrolled truncations that prevent a quantitative estimate of the error. --------- Pour plus d'informations, merci de contacter Kneur J.-L. |
