摘要：
We investigate how baryogenesis can occur by the presence of an f(T)-related gravitational term. We study various cases of f(T) gravity, and we discuss in detail the effect of the novel terms on the baryon-to-entropy ratio. Additionally, we study the constraints imposed by the observational values of the baryon-to-entropy ratio, and we discuss how more generalized cosmologies can contribute successfully, in a viable and consistent way, in the gravitational baryogenesis mechanism.
