|Summary of the project:|
Strong interactions are responsible for the stability of atomic nuclei. More than 25 years ago the theory of strong interactions, quantum chromodynamics (QCD), was formulated. It is now generally believed that this theory is able to explain and describe all properties of strongly interacting elementary particles.
In QCD, interactions of protons and neutrons, the building blocks of nuclei, are explained through interactions of their subconstituents, quarks and gluons, which have never been observed as free particles. The question of what is the underlying mechanism of the phenomenon of quark and gluon confinement remains a challenging problem of QCD. Our research group has devoted much effort in recent years to the study of various aspects of this question, using numerical simulations of quantum chromodynamics on a lattice. We have accumulated compelling evidence in favor of the model of confinement based on condensation of center vortices in the QCD vacuum.
The purpose of the present project is to continue the investigation of the center-vortex model of confinement and to study its consequences in considerable detail.
We will address these issues in further numerical simulations of lattice QCD, and also analytically in a simplified lower-dimensional model.
