Reconstructing ΛCDM f(T) gravity model with observational constraints

By restricting omega(eff) = -1 in this study, we rebuild a f(T) gravity function from a Lambda CDM model. The equation for obtaining the f(T) function is f(T) = 1/2T - 2 alpha(-T)(1/ 2) - beta, where alpha and beta are positive constants. A flat FLRW space-time metric has been taken into account, and modified field equations for the Hubble function and scaling factor have been solved. With two observational datasets, H(z) and SNe Ia data, we placed observational constraints on the Hubble function and apparent magnitude m(z) and we were able to determine the model parameters with the best match. These numbers have been used to analyze a number of cosmic phenomena occurring in the expanding cosmos. We have discovered a Lambda model-closed transit phase decelerating to accelerating universe model.
