Two-loop dimension Six Effective Action: Integrating Out Heavy Scalar
Nilabhra Adhikary, Jaydeb Das, Debmalya Dey
For the first time, we present the model-independent two-loop effective action up to dimension six after integrating out heavy scalar(s) employing the Heat-Kernel method. We comput…

Electroweak Scalar Effects Beyond Dimension-6 in SMEFT
Nilabhra Adhikary, Tisa Biswas, Joydeep Chakrabortty +2
The Standard Model Effective Field Theory (SMEFT) provides a robust framework for probing deviations in the couplings of Standard Model particles from their theoretical predictions…
