Emergence of running vacuum energy in $f(R,T)$ gravity : Observational constraints

Ahmed Errahmani, Mounia Magrach, Safae Dahmani +2

In this work, we present a new analysis for $f(R,T)$ gravity by exploring the energy momentum tensor. We demonstrate that $f(R,T)$ gravity with the form $f(R,T)=R+2{\kappa }^2\lambda T-2\Lambda$ is e…
