- Gauge Theories on the Light-Front Stanley J. Brodsky Física, Astronomía y Matemáticas The light-front quantization of gauge theories in light-cone gauge provides a frame-independent wavefunctionrepresentation of relativistic bound states, simple forms for current matrix elements, explicit unitary, and atrivial vacuum. The light-front Hamiltonian form of QCD provides an alternative to lattice gauge theory for thecomputation of nonperturbative quantities such as the hadronic spectrum and the corresponding eigenfunctions.In the case of the electroweak theory, spontaneous symmetry breaking is represented by the appearance ofzero modes of the Higgs field. Light-front quantization then leads to an elegant ghost-free theory of massivegauge particles, automatically incorporating the Lorentz and t Hooft conditions, as well as the Goldstone bosonequivalence theorem. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46400102 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1A Vol.34
