EFT Diagrammatica: UV Roots of the CP-conserving SMEFT
Supratim Das Bakshi, Joydeep Chakrabortty, Suraj Prakash +2
Effective Field Theories are an established framework to bridge the gap between UV and low energy theories. In the context of the Standard Model, the bottom-up approach extends its…

Effective Operator Bases for Beyond Standard Model Scenarios: An EFT compendium for discoveries
Upalaparna Banerjee, Joydeep Chakrabortty, Suraj Prakash +2
It is not only conceivable but likely that the spectrum of physics beyond the Standard Model (SM) is non-degenerate. The lightest non-SM particle may reside close enough to the ele…
