From Quantum Unstable Systems to the Decaying Dark Energy: Cosmological Implications

Figure 5

The diagram of the evolution of the parameter with respect to the cosmological time . For illustration, two example values of the parameter are chosen: (the top green curve) and (the middle red curve). For comparison the CDM model with the parameter is represented by the bottom blue curve. Here, the value of the parameter is equal to 1. The cosmological time is expressed in .
