Limites para uma gravitação com possíveis efeitos quânticos

Abstract

Recently it was shown that quantum corrections to the Newton potential can explain the rotation curves in spiral galaxies without introducing the Dark Matter halo. The unique phenomenological parameter aѵ of the theory grows with the mass of the galaxy. In order to better investigate the mass-dependence of aѵ one needs to check the upper bound for aѵ at a smaller scale. Here we perform the corresponding calculation by analyzing the dynamics of the Laplace-Runge-Lenz vector and the equilibrium condition of white-dwarf. The resulting limitation on quantum corrections is suggesting a mass-dependence of aѵ.
