本文研究了依赖比例依赖性重力的宇宙学模型。重力动作被认为是辅助常数的爱因斯坦 - 希尔伯特术语，其中$ g_k $和$λ_k$的耦合与能量尺度$ k $一起运行。 ％ 另外，请注意，通过建筑，我们的形式主义在纽顿恒定的耦合的极限时恢复了一般相对论。 ％ 基于比例依赖性宇宙学模型的两个子模型面临着最新的观察数据： i）哈勃参数$ h（z）$， ii）距离模量$μ（z）$和iii）Baryon声学量表演变作为红移（BAO）的功能。 ％ 讨论了模型的生存能力，获得了这些可观察物的最佳拟合参数和最大似然轮廓。最后，对$ h（z）$+$μ（z）$+bao进行联合分析。
This paper examines a cosmological model of scale-dependent gravity. The gravitational action is taken to be the Einstein-Hilbert term supplemented with a cosmological constant, where the couplings, $G_k$ and $Λ_k$, run with the energy scale $k$. % Also, notice that, by construction, our formalism recovers general relativity when in the limit of constant Newton's coupling. % Two sub-models based on the scale-dependent cosmological model are confronted with recent observational data from: i) the Hubble parameter $H(z)$, ii) distance modulus $μ(z)$, and iii) baryon acoustic scale evolution as functions of redshift (BAO). % The viability of the model is discussed, obtaining the best-fit parameters and the maximum likelihood contours for these observables. Finally, a joint analysis is performed for $H(z)$+$μ(z)$+BAO.
