The torsion of spacetime, if it exists, plays an important role at the very early universe, when the spin density of particles was very high. It is generally believed that in the extremely high energies of the early universe a new physics called trans-Planckian physics should be considered. Since the initial conditions for inflation are probably a result of this new physics, here we consider spin and torsion as trans-Planckian effects and analyze their influence on the power spectrum of scalar and tensor perturbations at the end of the inflationary era.
