Abstract: (Elsevier)
The method first applied by Good to determine the gravitational mass difference ΔM g between the K 0 and K 0 mesons is repeated using recent measurements of the parameters of neutral K meson decays and of the location and mass of the supergalactic centre. The ratio ΔM g / M ⩽2×10 −13 , which constitutes one of the severest tests of the weak equivalence principle.
  • mass difference: (K0 anti-K0)
  • gravitation: potential
  • K0: nonleptonic decay
  • numerical calculations: interpretation of experiments
