Electric Dipole Moments as Precision Probes of CP-Violating Top-Quark Interactions in SMEFT
Subhajit Kala, Soumitra Nandi, Sonakshi Saha
Electric dipole moments (EDMs) provide some of the most sensitive probes of CP-violating interactions beyond the Standard Model (SM). Within the Standard Model Effective Field Theo…
Anomalous Dimensions, Matching, and Phenomenology of Dirac Fermionic Dark Matter Effective Interactions
Subhajit Kala, Lipika Kolay, Soumitra Nandi
We explore a fermionic dark matter (DM) extension of the Standard Model Effective Field Theory (SMEFT) and establish a complete renormalisation-group framework for its phenomenolog…
Exploring -mediated heavy FCNCs at the FCC-ee
Abhik Sarkar, Subhajit Kala, Amir Subba +1
The flavor structure of the Standard Model (SM) remains one of the most compelling questions in particle physics, with the third generation being particularly intriguing due to its…
A Study on Top Quark FCNC Interactions in SMEFT Framework
Subhajit Kala, Soumitra Nandi
We present a model-independent study of rare flavour-changing neutral current (FCNC) interactions of the top quark within the Standard Model Effective Field Theory (SMEFT). Matchin…
