论文摘要
重力男性生成在重子不对称的研究中起重要作用。但是，在辐射中，重力男性生成的原始机制占主导的ERA导致不对称因子$η$等于零，这表明该机制可能不会为标准宇宙学模型产生足够的Baryon不对称性。在本手稿中，我们通过使用新的高阶普遍不确定性原理（GUP）研究了早期宇宙中生成重子不对称的重力男性生成。证明，由于高阶GUP的影响，宇宙的熵和弗里德曼方程偏离了原始情况。这些修饰打破了宇宙的热平衡，进而产生非零的不对称因子$η$。特别是，我们的结果满足了所有三个萨哈罗夫条件，这表明在高阶GUP框架中解释Baryon不对称的方案是可行的。此外，将我们的理论结果与观察结果面对面，我们约束了GUP参数$β_0$，其绑定在$ 8.4 \ times {10^{10}}} \ sim 1.1 \ sim 1.1 \ times {10^{13}} $。
The gravitational baryogenesis plays an important role in the study of the baryon asymmetry. However, the original mechanism of gravitational baryogenesis in the radiation dominated era leads to the asymmetry factor $η$ is equal to zero, which indicates this mechanism may not generate a sufficient baryon asymmetry for the standard cosmological model. In this manuscript, we investigate the gravitational baryogenesis for the generation of baryon asymmetry in the early Universe by using an new higher-order generalized uncertainty principle (GUP). It is demonstrated that the entropy and Friedman equation of the Universe deviate from the original cases due to the effect of the higher-order GUP. Those modifications break the thermal equilibrium of the Universe and in turn produces a non-zero asymmetry factor $η$. In particular, our results satisfy all three Sakharov conditions, which indicates that the scheme of explaining baryon asymmetry in the framework of higher-order GUP is feasible. In addition, confronting our theoretical results with the observational results, we constraint the GUP parameter $β_0$, whose bound between $8.4 \times {10^{10}} \sim 1.1 \times {10^{13}}$.
