论文摘要
我们考虑在宇宙学框架中扭转重力的有效野外理论表述，以改变背景演变。然后，我们使用SH0ES团队的最新$ H_0 $测量以及来自Cosmic Chronometer（CC）和径向Baryon声学振荡（BAO）的观察性哈勃数据，并通过应用高斯流程以模型独立的方式重建$ f（t）$形式。由于特殊的平方根项不影响背景级别的演变，因此我们最终总结了一个可以产生数据所需的背景进化的函数家族。最后，使用多项式函数进行拟合，并实施贝叶斯信息标准（BIC），我们找到了一个分析表达式，可以描述宇宙学的演变与观察结果非常吻合。
We consider the effective field theory formulation of torsional gravity in a cosmological framework to alter the background evolution. Then we use the latest $H_0$ measurement from the SH0ES Team as well as observational Hubble data from cosmic chronometer (CC) and radial baryon acoustic oscillations (BAO) and we reconstruct the $f(T)$ form in a model-independent way by applying Gaussian processes. Since the special square-root term does not affect the evolution at the background level, we finally summarize a family of functions that can produce the background evolution required by the data. Lastly, performing a fitting using polynomial functions, and implementing the Bayesian Information Criterion (BIC), we find an analytic expression that may describe the cosmological evolution in great agreement with observations.
