@article{Camera2014DetectabilityOT, title={Detectability of torsion gravity via galaxy clustering and cosmic shear measurements}, author={Stefano Camera and Vincenzo F. Cardone and Ninfa Radicella}, journal={Physical Review D}, year={2014}, volume={89}, pages={083520} }

Alterations of the gravity Lagrangian introduced in modified torsion gravity theories---also referred to as $f(T)$ gravity---allows for an accelerated expansion in a matter dominated Universe. In this framework, the cosmic speed up is driven by an effective `torsion fluid'. Besides the background evolution of the Universe, structure formation is also modified because of a time dependent effective gravitational constant. Here, we investigate the imprints of $f(T)$ gravity on galaxy clustering…
