A Comprehensive Study on Top Quark FCNC Interactions in SMEFT Framework
Subhajit Kala, Soumitra Nandi
We present a comprehensive, model-independent analysis of rare flavour-changing neutral current (FCNC) interactions of the top quark within an effective field theory framework. Beg…
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…
Magnetically Induced Schrödinger Cat States: The Shadow of a Quantum Space
Partha Nandi, Nandita Debnath, Subhajit Kala +1
Schrödinger cat states, which are superpositions of macroscopically distinct states, are potentially critical resources for upcoming quantum information technologies. In this pape…
Quantum ballet by gravitational waves: Generating entanglement's dance of revival-collapse and memory within the quantum system
Partha Nandi, Bibhas Ranjan Majhi, Nandita Debnath +1
Recent proposals are emerging for the experimental detection of entanglement mediated by classical gravity, carrying significant theoretical and observational implications. In fact…
