The article communicates gravitational baryogenesis in non-minimal f(T) gravity and f(T,B) teleparallel gravity where T denote the torsion scalar and B a boundary term. These extended teleparallel theories of gravity differ from the usual f(T) gravity and therefore could provide key insights in expounding the baryon asymmetry of the universe. Furthermore, such a study also put constraints on the model parameters of these extended teleparallel theory of gravity. I present different baryogenesis interactions proportional to iT, if(T), i(T+B) and if(T+B) and find that both of these teleparallel theories of gravity yield viable estimates of the baron-to-entropy ratio compatible with observations except for the baryogenesis interaction proportional to i(T+B). It is therefore encouraging to exercise these extended theories of gravity in other cosmological areas to under their efficiency and applicability in characterizing the current state of the universe.

扩展的遥平行重力理论中的引力重生

文章以非最小的方式传达了重力重生 FŤ 重力和 FŤ 远心重力 Ť 表示扭转标量和 边界项。这些扩展的引力平行引力理论不同于通常的FŤ引力,因此可以为阐明宇宙的重子不对称性提供重要的见识。此外,这样的研究还限制了这些扩展的远平行重力理论的模型参数。我提出了与重整成正比的不同相互作用一世Ť一世FŤ一世Ť+一世FŤ+ 并发现这两种远心平行引力理论都产生了与观测值相容的男爵与熵之比的可行估计,除了成正比相互作用与 一世Ť+。因此,鼓励在其他宇宙学领域中运用这些扩展的引力理论,使其在表征宇宙当前状态的效率和适用性范围内。
