摘要：

We present here an extended abstract of the results derived in [1]. We study the decay of the inflaton field to another scalar field X in the parametric resonance preheating mechanism. We consider the presence of several simultaneous couplings between the fields. We show that the contribution for the X field energy density of the higher harmonic is a small fraction of that of the fundamental frequency, and so the presence of a finite number of higher harmonics has limited cosmological implications
