Abstract

We consider the possibility of the quantum vacuum states in [Formula: see text] gravity. Particularly, we study the Bogoliubov transformations associated to different vacuum states for some [Formula: see text] models. The method consists of fixing the [Formula: see text] free parameters by requiring the Bogoliubov coefficients to be minimized. In such a way, the particle production is related to the value of the Hubble parameter and also the given [Formula: see text] model.
