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…

Viscous Dark Energy and Mass-Varying Dark Matter in Lyra Manifold: Cosmological Dynamics and Observational Constraints
Giridhari Deogharia, Madhurima Pandey, Ashadul Halder
We investigate the cosmological dynamics of a universe described by Lyra's geometry in the presence of dark energy (DE) and dark matter (DM). Dark energy is modeled as a quintessen…

Exploring the effects of dark matter - dark energy interaction on cosmic evolution in viscous dark energy scenario
Ashadul Halder, Madhurima Pandey, Rupa Basu +1
We explore the influence of interactions between dark matter (DM) and dark energy (DE) on the cosmic evolution of the Universe within a viscous dark energy (VDE) framework. Moving…
