Yukawa scalar self energy at two loop and $⟨\ddot{I}{•}^2⟩$ in the inflationary de Sitter spacetime

Sourav Bhattacharya, Moutushi Dutta Choudhury

We have considered the Yukawa theory at two loop in the inflationary de Sitter spacetime, for a massless minimally coupled scalar and a massless fermion. The one loop computation f…
