# $f(T,B)$ cosmography for high redshifts

@inproceedings{EscamillaRivera2021fTBCF, title={\$f(T,B)\$ cosmography for high redshifts}, author={Celia Escamilla-Rivera and Geovanny A. Rave-Franco and Jackson Levi Said}, year={2021} }

In light of the statistical performance of cosmological observations, in this work we present the cosmography in f(T,B) gravity. In this scenario we found a cosmological viable standard case that allows to reduce the degeneracy between several f(T,B) models already proposed in the literature. Furthermore, we constrain this model using Pantheon SNeIa compilation, Cosmic Chronometers and a newly GRB calibrated data sample. We found that with an appropriate strategy for including the cosmographic…
