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…
Constraining anomalous and related SMEFT couplings using low-energy and electroweak precision observables
Subhajit Kala, Lipika Kolay, Lopamudra Mukherjee +1
We investigate constraints on couplings of Standard Model effective field theory (SMEFT) operators contributing to effective vertex at tree level. We study the one-loop level…
