Running vacuum in quantum field theory in curved spacetime: renormalizing $$\rho _{vac}$$ ρvac without $$\sim m^4$$ ∼m4 terms

Abstract The $$\Lambda $$ Λ -term in Einstein’s equations is a fundamental building block of the ‘concordance’ $$\Lambda $$ Λ CDM model of cosmology. Even though the model is not free of fundamental problems, they have not been circumvented by any alternative dark energy proposal either. Here we sti...
