Generating primordial fluctuations from modified teleparallel gravity with local Lorentz-symmetry breaking
In the context of modified teleparallel gravity, we study the generation of primordial density fluctuations in a general scalar-torsion theory whose Lagrangian density is an arbitrary function f(T,ϕ) of the torsion scalar T and a scalar field ϕ, plus the kinetic term of this latter. It is well known...
