dc.description.abstractIn this work we use momentum-space techniques to evaluate the propagator G(x
dc.description.abstractx') for a spin 1/2 mass dimension one spinor field on a curved Friedmann-Robertson-Walker spacetime. As a consequence, we built the one-loop correction to the effective lagrangian in the coincidence limit. Going further we compute the effective lagrangian in the finite temperature regime. We arrive at interesting cosmological consequences, as time-dependent cosmological 'constant', fully explaining the functional form of previous cosmological models.
