%X We extend the Standard Model with a scalar warm dark matter field <em>S</em> with an interaction <img src=\"Edit_7568c957-59cc-42f7-a6b1-027a4ee53e1f.png\" alt=\"\" />with the Higgs boson <span style=\"white-space:nowrap;\"><em>&amp;empty;</em></span>. This warm dark matter scenario is in agreement with cosmological observations if <em>S</em> and <span style=\"white-space:nowrap;\"><em>&amp;empty;</em>&nbsp;</span>come into thermal and diffusive equilibrium before the temperature drops below the Higgs boson mass <em>m</em><sub><em>H</em></sub>. We study inflation driven by the fields <span style=\"white-space:nowrap;\"><em><span style=\"white-space:nowrap;\">&amp;empty;</span></em></span> or <em>S</em>, and also study preheating and reheating, in order to constrain the parameters of this extension of the Standard Model. It is remarkable that, with the current data, these models pass a closure test with no free parameters.
