SM (Standard Model) extensions

Standard Model extensions are theoretical frameworks that build upon the Standard Model of particle physics, which successfully describes the fundamental particles and forces in the universe. These extensions aim to address unanswered questions, such as dark matter, neutrino masses, and the matter-antimatter asymmetry. By incorporating new particles or forces, these extensions seek to provide a more complete understanding of the universe's workings beyond the limitations of the Standard Model, potentially revealing deeper truths about the nature of reality and guiding future experiments in particle physics.
