Endowing ? with a dynamic nature: constraints in a spatially curved Universe

School
PARTICLES AND ACCELERATORS

Abstract: In this study, we consider three dark energy models in which $Lambda$ is not constant, but has a dynamic nature that depends on the Hubble parameter $H$ and/or its time derivative $dot{H}$.
We analyze the generalized running vacuum model, for which $Lambda(H)=A+BH^2+Cdot{H}$, along with the two models obtained by setting $B$ or $C$ equal to zero. A null value for $C$ yields the classical running vacuum model (RVM), while $B=0$ corresponds to what we term the generalized running vacuum sub-case, or GRVS. Our main aim is to investigate whether these models can accommodate non-zero spatial curvature. To this end, we carry out a ...
