Classical inflaton field induced creation of superheavy dark matter
We calculate analytically and numerically the production of superheavy dark matter (X) when it is coupled to the inflaton field \phi within the context of a slow-roll m_\phi^2 \phi^2/2 inflationary model with coupling g^2 X^2 \phi^2/2. We find that X particles with a mass as large as 1000 H_i, where …
