DESCRIPTION:Speakers: Neil Christensen (Illinois State University)\n\nThis
  talk surveys the central ideas and recent progress of the Constructive St
 andard Model\, an approach to particle physics that builds interactions di
 rectly from physical degrees of freedom rather than from gauge-dependent f
 ield variables. I begin by explaining why this viewpoint is useful\, using
  the photon as an example: in the traditional formulation\, unphysical com
 ponents appear in intermediate steps and must cancel from observable predi
 ctions\, while constructive methods avoid these redundancies from the outs
 et. I then review the main conceptual advances and results from my work\, 
 including the role of little-group-based variables and the development of 
 a field-theory framework that reproduces constructive vertices while maint
 aining the desired physical principles. Overall\, the talk highlights both
  the conceptual clarity and the practical power of the constructive approa
 ch to the Standard Model.\n\nhttps://indico.global/event/16622/
