Classical inflaton field induced creation of superheavy dark matter

  title={Classical inflaton field induced creation of superheavy dark matter},
  author={Daniel J. H. Chung},
We calculate analytically and numerically the production of superheavy dark matter (X) when it is coupled to the inflaton field φ within the context of a slow-roll mφφ /2 inflationary model with coupling gXφ/2. We find that X particles with a mass as large as 1000 Hi, where Hi is the value of the Hubble expansion rate at the end of inflation, can be produced in sufficient abundance to be cosmologically significant today. This means that superheavy dark matter may have a mass of up to 10−3MPl… CONTINUE READING
