Our
field of research is Quantum Chromodynamics (QCD), the fundamental
theory of strong interactions, which bind quarks to form protons and
neutrons, the basic constituents of nuclei in atoms. Although QCD
has been known for 30
years we are still very far from a complete solution of the theory.
QCD is different from all known fundamental theories in that it is a
confining theory, i.e. it forbids break-up of hadrons into their
constituent quarks. This property poses fundamental difficulties in
applying to QCD the classical analytical methods of Quantum Field
Theory which were very successful in solving Quantum
Electrodynamics.
The best method, at present, to evaluate hadronic observables is
using the discrete
version of QCD known as Lattice QCD proposed by K. Wilson in 1974.
Such calculations can only be carried out by numerical simulation
and usually require the
fastest and biggest
supercomputers. Our research focuses on several aspect of Lattice
QCD. In this research we are collaborating
with other Institutes both in Europe and in the
US. |
