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 Fermion(s)
Joydeep Chakrabortty, Shakeel Ur Rahaman, Kaanapuli Ramkumar
We present the universal one-loop effective action up to dimension eight after integrating out heavy fermion(s) using the Heat-Kernel method. We have discussed how the Dirac operat…
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…
EFT, decoupling, Higgs boson mixing, and higher dimensional operators
Upalaparna Banerjee, Joydeep Chakrabortty, Christoph Englert +3
The effective field theory (EFT) framework is a precise approximation procedure when the inherent assumptions of a large-scale separation between the Standard Model (SM) and new in…
