N2 - In a world with an axion the precise measurement of gravitational forces and checks of the equivalence principle at small distances, λ∼1 cm and less, could provide an additional test of CP symmetry. Using the chiral approach, we connect the strength of the CP-odd axion-nucleon vertex with the CP-odd pion-nucleon coupling for color electric dipole moments of quarks as a low-energy source of CP violation. Strong limits on CP-odd coupling gπNN coming from atomic electric dipole moments give the best limits on the long range force mediated by axions, Faxion/ Fgravity<2.10-10(1 cm/λ)2.
