Higher-Derivative Lee-Wick Unification

Understand

We consider gauge coupling unification in Lee-Wick extensions of the Standard Model that include higher-derivative quadratic terms beyond the minimally required set.

• We determine how the beta functions are modified when some Standard Model particles have two Lee-Wick partners.
• We show that gauge coupling unification can be achieved in such models without requiring the introduction of additional fields in the higher-derivative theory and we comment on possible ultraviolet completions.
