Signals from Fermionic inflationary cosmology with Yukawa interaction

Lin-Hong Sui, Dan Li, Jia-Ze Sun +1

We investigate an inflationary model wherein the Dirac field $\ddot{I}ˆ$ is directly coupled to a scalar inflaton $\ddot{I}•$ via a Yukawa interaction $g\ddot{I}•\bar{\ddot{I}}ˆ\ddot{I}ˆ$ and examine the resulting obs…
