Probing Fermion-Portal Scalar Dark Matter through Charged Vector-Like Fermions at Future Muon Colliders

Songshaptak De, Tapoja Jha, Najimuddin Khan +1

We revisit a minimal fermion-portal scalar dark matter model consisting of a real singlet scalar dark matter candidate and additional vector-like singlet and doublet charged fermio…

Unfolding quantum entanglement from at a muon collider

Songshaptak De, Atri Dey, Tousik Samui

We explore the potential to study quantum entanglement through Bell-type inequalities in Higgs boson decays at a future muon collider. Our analysis focuses on the channel $μ^+ μ^…

Jet Substructure Analysis for Distinguishing Left- and Right-Handed Couplings of Heavy Neutrino in Decay at the HL-LHC

Songshaptak De, Atri Dey, Tousik Samui

The search for heavy bosons in their decay modes to a lepton and a heavy neutrino offers a promising avenue for probing new physics beyond the Standard Model. This work focuse…

Measuring the polarization of boosted, hadronic bosons with jet substructure observables

Songshaptak De, Vikram Rentala, William Shepherd

In this work, we present a new technique to measure the longitudinal and transverse polarization fractions of hadronic decays of boosted bosons. We introduce a new jet substruc…
