Cosmological constraints on the interacting viscous dark matter and decaying vacuum energy models
Lokesh Chander, C P Singh
We investigate an interacting dark sector scenario in which a deviation from the standard dilution law of cold dark matter is parametrized by a perturbative correction , thereby…

Decaying vacuum energy, matter creation and cosmic acceleration
Lokesh Chander, C P Singh
We discuss an interacting dark sector model featuring decaying vacuum energy and dark matter empowered by gravitationally induced matter creation. Motivated by quantum field theore…
