| Research Abstract |
Quarks are elementary particles which reside in atomic nuclei. In this research project, we performed precise theoretical computations for explaining the nature of the physical systems composed by a quark and its anti-particle. In particular, we completed computation of the interquark force which has been demanded for more than a decade. The result has a lot of applications and has already been applied to preliminary determinations of quark masses and other physical parameters. Furthermore, we constructed a theoretical framework which is necessary for determining the top quark mass accurately at the current LHC experiment.
