[IP2I seminar] S. Kala (IIT Guwahati, India) - Probing Top Quark Anomalous Effective Couplings Through Precision Studies in SMEFT Frameworks

The top quark is expected to be particularly sensitive to new physics effects due to its large Yukawa coupling and close connection to the electroweak symmetry-breaking sector. I present a comprehensive SMEFT analysis of top-quark flavour-changing neutral-current and charged-current effective interactions, using constraints from flavour physics, electroweak precision observables, Higgs measurements, and electric dipole moments. The resulting bounds significantly improve existing limits on several top-quark effective couplings and provide new constraints on CP-violating interactions. Implications for rare top decays and future collider searches will also be discussed.
