Description:
Author(s): Habib Abedi, Salvatore Capozziello, Rocco D’Agostino, and Orlando Luongo In the present study, we consider an extended form of teleparallel Lagrangian f ( T , ϕ , X ) , as function of a scalar field ϕ , its kinetic term X and the torsion scalar T . We use linear perturbations to obtain the equation of matter density perturbations on sub-Hubble scales. The gravitational coupling is... [Phys. Rev. D 97, 084008] Published Fri Apr 06, 2018
