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…
Sustained growth of quantum circuit complexity in many-body Hamiltonian dynamics
Wonjun Lee, Saúl Pilatowsky-Cameo, Soonwon Choi
The quantum circuit complexity of an evolving many-body quantum system is believed to exhibit a sustained growth, maintained for timescales much longer than the onset of thermaliza…
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…
Probing Invisible Fermions in via Angular Observables
Lipika Kolay, Soumitra Nandi, Shantanu Sahoo
Semileptonic decays provide a sensitive probe of light invisible particles, such as sterile neutrinos or dark-sector fermions. Within a general we…
Probing Light Dark Fermions in via Rate Distributions
Lipika Kolay, Soumitra Nandi, Shantanu Sahoo +1
Experimental analyses of the semileptonic decays typically rely on the assumption that the missing energy originates from a massless neutrino, as predic…
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…
Flavour and Electroweak Precision Constraints on a Simplified Dark Matter Model with a Light Spin-0 Mediator
Lipika Kolay, Soumitra Nandi
This work investigates the allowed parameter spaces of a simplified dark matter (DM) model characterized by a spin-0 mediator with masses in the low to intermediate range ( 10…
Exploring Constraints on Simplified Dark Matter Model Through Flavour and Electroweak Observables
Lipika Kolay, Soumitra Nandi
This study focuses on a combined analysis of various available inputs to constrain the parameter spaces of a simplified dark matter (SDM) model featuring a spin-0 mediator and ferm…
Probing flavor constrained SMEFT operators through production at the Muon collider
Subhaditya Bhattacharya, Sahabub Jahedi, Soumitra Nandi +1
We investigate flavour violating four Fermi Standard Model Effective Field Theory (SMEFT) operators of dimension-six that can be probed via production at…
