ABSTRACT: Current accelerated expansion of our universe, as indicated by number of observations, is addressed in the present work. Like several works in literature, we postulate dark energy as candidate and search for scalar field and
f(
T
)
model susceptible to reproducing this negative pressure and dominant component of our universe. By considering hybrid cosmology whose free parameters are recently constrained with observational data, our numerical analysis promotes quintessence-like evolution very close to ΛCDM model as predicted by Ia supernovae observations. Furthermore, the analytical results do not exclude the possibility of falling into phantom-like evolution for suitable choice of the free parameters. The approach followed here directly links the scalar field to the
f(
T
)
function and permits obtaining a dark energy-like
f(
T
)
model in accordance with observational data.
