Production of Dirac particles due to Riccion coupling

  • S. K. Srivastava
  • K. P. Sinha


It has been noted that at high energy the Ricci scalar is manifested in two different ways, as a matter field as well as a geometrical field (which is its usual nature even at low energy). Here, using the material aspect of the Ricci scalar, its interaction with Dirac spinors is considered in four-dimensional curved space-time. We find that a large number of fermion-antifermion pairs can be produced by the exponential expansion of the early universe.
