Chiral symmetry and light-front zero modes: state of the art and a fresh look

Description
A brief review of past light-front (LF) approaches to chiral-symmetry breaking and to LF zero modes is presented. A quantum-mechanical treatment of the dynamical zero modes and their corresponding vacuum potential leading to "measurable" effects in a two-dimensional non-abelian model will be briefly discussed. Then a novel second-quantized picture of the dynamical LF zero modes will be formulated, along with its relation to non-trivial LF vacuum structure and chiral symmetry of a fermionic model.
