The macroscopic quantum-vacuum theory allows us to distinguish between different phenomenological f(R) models on physical grounds.6 pages, v4: this archive version corresponds to the published version with a few minor correctionsGeneral Relativity and Quantum CosmologyAstrophysicsOther Condensed MatterHigh Energy Physics - Theorytext
