Physics on the Light-Front and Novel QCD Phenomena

Theoretical Physics, general interest

I will survey a number of exciting new developments in hadron physics which can be derived from the underlying conformal properties of quantum chromodynamics and the application of Dirac's boost-invariant light-front quantization. Light-front holography, together with superconformal algebra, has provided new insights into the physics of color confinement, the spectroscopy and dynamics of hadrons, the origin of the QCD mass scale, the QCD running coupling, as well as surprising supersymmetric relations between the masses of mesons, baryons, and tetraquarks. I also will discuss a number of novel features of QCD, such as color transparency, hidden color, intrinsic heavy quark phenomena, and factorization-breaking lensing effects.
