(2019). f(R, T) models applied to baryogenesis.The European Phyhsikcal Journal. Pg 1-6.https://doi.org/10.1140/epjc/s10052-019-6559-0http://hdl.handle.net/123456789/1406Since antiparticles were first predicted and observed [1], it has been clear that there exist high degree of matter antimatter symmetry. This observation is a stark contradiction to the phenomena of everyday and cosmological evidence, particularly the fact that our universe consists of almost entirely matter with little primordial antimatter.This paper is devoted to the reproduction of the gravitational baryogenesis epoch in the context of f (R, T ) theory of gravity, where R and T are respectively the curvature scalar and the trace of the energy-momentum tensor, respectively. It is assumed a minimal coupling between matter and gravity. In particular we consider the following two models, f (R, T ) = R + αT + βT 2 and f (R, T ) = R + μR2 + λT , with the assumption that the universe is filled by dark energy and perfect fluid where the baryon to entropy ratio during a radiation domination era is non-zero. We constrain the models with the cosmological gravitational baryogenesis scenario, highlighting the appropriate values of model’s parameters compatible with the observation data of the baryon-entropy ratio.en-USgravitational baryogenesisenergy-momentumantiparticlesantimatterArticle
