AbstractMotivated by the discrepancy in measurements of H-0 between local and global probes, we investigate whether teleparallel gravities could be a better model to describe the present-day observations or at least to alleviate the H-0 tension. Specifically, in this work we study and place constraints on three popular f (T) models in light of the Planck-2018 cosmic microwave background data release. We find that the f(T) power-law model can alleviate the H-0 tension from 4.4 sigma to 1.9 sigma level, while the f(T) model of two exponentials fails to resolve this inconsistency. Moreover, for the first time, we obtain constraints on the effective number of relativistic species N(eff )and on the sum of the neutrino masses Sigma(m nu) in f(T) gravity. We find that the constraints obtained are looser than in Lambda CDM. However, the introduction of massive neutrinos into the cosmological model alleviates the H-0 tension for the power-law model. Finally, we find that whether a viable f (T) theory can mitigate the H-0 tension depends on the mathematical structure of the distortion factor y(z, b). These results could provide a clue for theoreticians to write a more physical-motivated expression of f(T) function.
