Renormalization and decoupling for the Yukawa model in curved spacetime
Sergi Nadal-Gisbert, Antonio Ferreiro, José Navarro-Salas
We consider the renormalization of the one-loop effective action for the Yukawa interaction. We compute the beta functions in the generalized DeWitt-Schwinger subtraction scheme. F…

Renormalization, running couplings and decoupling for the Yukawa model in curved spacetime
Antonio Ferreiro, Sergi Nadal-Gisbert, José Navarro-Salas
The decoupling of heavy fields as required by the Appelquist-Carazzone theorem plays a fundamental role in the construction of any effective field theory. However, it is not a triv…
