A New Solution to the Strong CP Problem

High Energy Physics - Phenomenology 2023-12-19 v1

Abstract

We suggest a new solution to the strong CP problem. The solution is based on the proper use of the boundary conditions for the QCD generating functional integral. We expand the perturbative boundary conditions to both perturbative and nonperturbative fields integrated in the QCD generating functional integral. It allows to nullify the CP odd term in the QCD Lagrangian and thus to solve the strong CP problem. The presently popular solution to the strong CP problem with introducing axions violates the principle of renormalizability of Quantum Field Theory, which is very successful phenomenologically. Our solution obeys the principle of renormalizability of Quantum Field Theory and does not involve new exotic particles like axions.
