From massive gravity to dark matter density
Abstract
Description
Massive gravity previously constructed as the spin-2 quantum gauge theory is studied in the classical limit. The vector-graviton field v which does not decouple in the limit of vanishing graviton mass gives rise to a modification of general relativity. The modified Schwarzschild solution contains a contribution which can be interpreted as the dark mass density. We calculate the density profile in the simplest spherically symmetric geometry.
