CP Violation

Big Bang Cosmology (background material)

Whystudy CP violation?

Broken symmetries in nature

- Symmetries have always been historically important in making discoveries

- Most symmetries are not broken

- Why is matter-antimatter symmetry different?

Connection with Cosmology

- CP violation is an important ingredient in baryogenesis

- Also has a word to say in models of leptogenesis

- Degree of violation not enough to generate the effects

Connection with New Physics

- Means of looking for new physics effects

- CP violation may indicate inconsistencies in Standard Model

A Lesson From History

  • New Physics shows up first at the intensity frontier

  • rather than at the energy frontier

  • GIM Mechanism used to predict 4th charm quark (core course)

  • CP Violation / CKM Matrix used to predict 5th/6th bottom/top quarks (this course)

  • Neutral currents found before discovery of Z

  • Top quark mass predicted from electroweak corrections in B physics

  • Higgs mass predicted from electroweak corrections W and Z bosons

  • Particularly sensitive loop processes

  • – new particles in internal loops

  • Standard model contributions suppressed /absent

  • Rare decays – flavour changing neutral currents

  • CP Violation

  • Lepton flavour / lepton number / lepton universality
