Christopher D. Carone (William, Mary)
TL;DR
This paper explores gauge coupling unification within Lee-Wick extensions of the Standard Model, demonstrating that unification can be achieved with higher-derivative terms and Lee-Wick partners without extra fields.
Contribution
It analyzes the impact of higher-derivative quadratic terms and multiple Lee-Wick partners on gauge coupling unification, providing a framework for unification without additional fields.
Findings
Gauge coupling unification is achievable with Lee-Wick extensions.
Modified beta functions depend on Lee-Wick partner multiplicity.
Unification occurs without introducing extra higher-derivative fields.
Abstract
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.
