Can gravity resolve the tension?
arXiv:2003.10095 · doi:10.1103/PhysRevD.102.063530
Abstract
Motivated by the discrepancy in measurements of between local and global probes, we investigate whether teleparallel gravities could be a better model to describe the present days observations or at least to alleviate the tension. Specifically, in this work we study and place constraints on three popular models in light of the Planck-2018 CMB data release. We find that the power-law model can alleviate the tension from to level, while the model of two exponential fail to resolve this inconsistency. Moreover, for the first time, we obtain constraints on the effective number of relativistic species and on the sum of the neutrino masses in gravity. We find that the constraints obtained are looser than in CDM. However, the introduction of massive neutrinos into the cosmological model alleviate the tension for the power-law model. Finally, we find that whether a viable theory can mitigate the tension depends on the mathematical structure of the distortion factor . These results could provide a clue for theoreticians to write a more physical-motivated expression of function.
