One-loop Effective Action up to any Mass-dimension for Non-degenerate Scalars and Fermions including Light-Heavy Mixing
Upalaparna Banerjee, Joydeep Chakrabortty, Shakeel Ur Rahaman +1
We propose a Heat-Kernel-based method to compute one-loop effective action up to any mass-dimension with arbitrary numbers of non-degenerate scalars and fermions. We demonstrate ou…

One-loop Effective Action up to Dimension Eight: Integrating out Heavy Scalar(s)
Upalaparna Banerjee, Joydeep Chakrabortty, Shakeel Ur Rahaman +1
We present the complete one-loop effective action up to dimension eight after integrating out degenerate scalars using the Heat-Kernel method. The result is provided without assumi…
