Statement of Goals and Priority Research Issues

The central issue addressed by the light-front dynamics community is

The rigorous description of hadrons and nuclei from first principles in quantum chromodynamics.

The main goals of research in light-front dynamics are

- The rigorous evaluation of masses and wave functions of hadrons using the light-front Hamiltonian of QCD;

- Hadronic and nuclear phenomenology based on fundamental quark and gluon dynamics;

- Confront and design crucial experimental tests at the new hadron facilities - JLAB, RHIC, LHC, JPARC, GSI(FAIR).

Advantages of the light-front framework

Boost-invariant wave functions which enable the calculation of decay rates, scattering amplitudes, correlations, spin effects, phases, distributions and other hadronic observables from first principles, as well as to illuminate novel QCD effects.

Challenges for the light-front framework

- Symmetry preserving regularization and renormalization methods,

- The incorporation of spontaneous symmetry breaking,

- Explicit evaluation of hadron spectra and amplitudes,

- Connections with string theory methods,

- Connections between quark-gluon and nuclear many-body methods.
