Abstract
The origin of matter domination in the Universe is one of the most exciting open puzzles in particle physics and cosmology. Despite many theoretical developments, the actual reason behind baryon-antibaryon asymmetry is still unknown. Our aim here is to examine this phenomenon in the framework of modified gravity theories, which have impressively elucidated the contemporary accelerated expansion of the Universe as well as the early phase. Consequently, this letter sets its sights on the task of constraining a specific variant of modified gravity, namely, f(Q) gravity, in conjunction with gravitational baryogenesis. The power law model and recently proposed DGP-like f(Q) models are considered to find the baryon-to-entropy ratio and compare them with the observed value, that is . Furthermore, we impose constraints on the additional degrees of freedom introduced by this modified theory of gravity.
