Dimension-Six Terms in the Standard Model Lagrangian

Understand

When the Standard Model is considered as an effective low-energy theory, higher dimensional interaction terms appear in the Lagrangian.

• Dimension-six terms have been enumerated in the classical article by Buchmueller and Wyler [3].
• Although redundance of some of those operators has been already noted in the literature, no updated complete list has been published to date.
• Here we perform their classification once again from the outset.
