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…
Complex Scalar Dark Matter with a Vector-Like Quark and Lepton: Precision, Flavor, and HL-LHC
Lipika Kolay, Rusa Mandal, Manimala Mitra +2
We investigate a minimal extension of the SM consisting of a -stabilized complex scalar dark matter (CSDM) candidate, a down-type vector-like quark (VLQ), and a charg…
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…
Up-type FCNC in presence of Dark Matter
Subhaditya Bhattacharya, Lipika Kolay, Dipankar Pradhan +1
Dark Matter (DM) is a known unknown. Apart, current experimental constraints on flavor-changing neutral current (FCNC) processes involving up-type quarks also provide scope to expl…
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…
Multiparticle scalar dark matter with symmetry
Subhaditya Bhattacharya, Lipika Kolay, Dipankar Pradhan
More than one dark sector particle transforming under the same symmetry provides one stable dark matter (DM) component which undergoes co-annihilation with the heavier particle(s)…
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…
