Scientific paper
In this series of lectures, I shall begin with the current investigations on phenomenology of hadron dynamics to demonstrate the importance of solving hadronic bound states within the framework of light-front (LF) QCD. Then, I will describe the basic procedure how to formulate the canonical theory of LFQCD, including light-front quantization of QCD, light-front gauge singularity, and light-front two-component formalism. I will also present a complete one-loop QCD calculation in terms of the light-front time-ordering perturbation theory, in comparison with the usual covariant perturbative QCD calculation. Following thereby I will discuss the development of heavy-quark effective theory and the manifestation of heavy quark symmetry on the light-front. Finally, by applying recently developed similarity renormalization group approach to light-front heavy quark effective theory, I will show a rigorous derivation of quark confinement interaction from LFQCD and its application to solve heavy hadron bound states.
