SUMMARY

This discussion centers on the report "CP Studies and Non-Standard Higgs Physics," which explores various non-standard Higgs scenarios that extend beyond the Standard Model. Key theories include two-Higgs-doublet models, minimal supersymmetric models with CP violation, and Little Higgs models. The report emphasizes the significance of these models in understanding CP violation and electroweak symmetry breaking, as well as their implications for collider physics and cosmology. It provides a comprehensive overview of theoretical aspects and potential experimental signatures relevant to the LHC and other colliders.

PREREQUISITES
  • Understanding of CP violation in particle physics
  • Familiarity with the Standard Model of particle physics
  • Knowledge of Higgs boson phenomenology
  • Basic concepts of collider physics and experimental signatures
NEXT STEPS
  • Research "two-Higgs-doublet models" and their implications for CP violation
  • Study "minimal supersymmetric models" and their role in Higgs physics
  • Explore "Little Higgs models" and their theoretical foundations
  • Investigate experimental techniques at the LHC for detecting non-standard Higgs signatures
USEFUL FOR

Particle physicists, researchers in theoretical physics, and experimental physicists focusing on Higgs boson studies and collider experiments will benefit from this discussion.

There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mixing between multiple Higgs bosons or other new scalar bosons. Alternatively, the Higgs may be a composite state, or there may even be no Higgs at all. These non-standard Higgs scenarios have important implications for collider physics as well as for cosmology, and understanding their phenomenology is essential for a full comprehension of electroweak symmetry breaking. This report discusses the most relevant theories which go beyond the Standard Model and its minimal, CP-conserving supersymmetric extension: two-Higgs-doublet models and minimal supersymmetric models with CP violation, supersymmetric models with an extra singlet, models with extra gauge groups or Higgs triplets, Little Higgs models, models in extra dimensions, and models with technicolour or other new strong dynamics. For each of these scenarios, this report presents an introduction to the phenomenology, followed by contributions on more detailed theoretical aspects and studies of possible experimental signatures at the LHC and other colliders.

Here's a non Standard Model hypothesis--the Higgs is the force that binds asymmetrical clusters (bags) of matter and antimatter quarks.
