Scientific paper

Inflationary cosmological models must include a process able to produce an evolution towards a phase of radiation domination so that Hot Big Bang is retrieved satisfactory. At the end of inflation, the universe enters to the stage known as (p)reheating during which cosmological reheating temperature should be increased in an explosive way. We study the process of preheating in a model that includes two scalar fields, one of which is the inflaton field, and four-leg interaction term in the Lagrangian.
