Adiabatic Particle Production with Decaying Λ and Anisotropic Universe
Sisir Bhanja, Subenoy Chakraborty, Ujjal Debnath
Abstract
Here we study an anisotropic model of the universe with constant energy per particle. A decaying cosmological constant and particle production in an adiabatic process are considered as the sources for the entropy. The statefinder parameters \r,s\ are defined and their behaviour are analyzed graphically in some cases.
