Gauge theories are the only way we know how to describe the fundamental interactions. In spite of all that has been learned regarding such theories, many fundamental questions remain unanswered. In particular, Quantum Chromo Dynamics (QCD), which is the gauge theory describing the strong interactions between quarks and gluons, continues to pose challenging questions for physicists. Quarks and gluons are confined at low temperature and matter density in the form of hadrons such as protons, neutrons and pions. The origin of confinement within QCD remains unexplained. Our limited progress on this problem is largely due to our ignorance of how to deal with intrinsically non-perturbative regimes of generic gauge theories.
The main research objective of the team will be to develop new techniques for the description of both perturbative and non-perturbative regimes of gauge theories and to use these techniques in phenomenological studies directly related to the results of current experiments. The entire project will lead to a deeper understanding of strong interactions and the phase diagram of QCD and QCD-like theories (as function of temperature, matter density, etc.). The confinement mechanism and its relation with chiral symmetry breaking will also be clarified. A detailed knowledge of the QCD phase diagram is essential for a number of physical applications ranging from early universe dynamics to the structure of cold and dense astrophysical objects. A better knowledge of strongly interacting theories is also needed to model possible extensions of the standard model of particle interactions and for solving fundamental cosmological problems. Finally, we need new and general methods to address the strong interaction problem, which is central in virtually all fields of physics.
