Quantum aspects of Yukawa model with scalar and axial scalar fields in curved spacetime
Iosif L. Buchbinder, Andreza Rairis Rodrigues, Eduardo Antonio dos Reis +1
We study the Yukawa model with one scalar and one axial scalar fields, coupled to copies of Dirac fermions, in curved spacetime background. The theory possesses a reach set of…

Renormalization of Yukawa model with sterile scalar in curved space-time
Vítor Fernandes Barra, Iosif L. Buchbinder, Jarme Gomes Joaquim +2
We explore the classical and quantum properties of a sterile scalar field coupled to copies of Dirac fermions in an external gravitational field. We find that the self-interact…
