Renormalization of Yukawa model with sterile scalar in curved space-time

We explore the classical and quantum properties of a sterile scalar field coupled to \(N\) copies of Dirac fermions in an external gravitational field. We find that the self-interaction scalar potential of a model that is consistent at the quantum level, includes odd (first and third) powers of a sc...
