Constraints on running vacuum model with $H(z)$ and $f{\sigma }_8$

Chao-Qiang Geng, Chung-Chi Lee, Lu Yin

We examine the running vacuum model with $\Lambda (H)=3\nu H^2+{\Lambda }_0$, where $\nu$ is the model parameter and ${\Lambda }_0$ is the cosmological constant. From the data of the cosmic microwave backg…
