Gauge Vectors-Tensor Gravity

We review and extend the Gauge Vectors-Tensor gravity: a covariant theory of gravity composed of a metric and gauge fields, leading to simple second order partial differential equations of motion, whose Newtonian and strong limits coincide to those of the Einsten-Hilbert action but the physics of its very weak fields should be identified through observation. We show that GVT is at least as dynamically stable as the Einstein-Hilbert gravity. It accommodates the MOND paradigm. We study its gravitational light deflection. We show that the post Newtonian parameter of $γ$ vanishes in the MOND regime of GVT gravity. Since $Λ$CDM assumes that $γ=1$, this suggests to observationally measure the $γ$ parameter in the weak regime of gravity as either a test for $Λ$CDM or GVT models
