Precise measurement of the $\eta$ and $K^{0}$ masses

New measurements of the $\eta$ and $K^{0}$ masses have been performed using decays into $3\pi^{0}$ with the NA48 detector at the CERN SPS. Using symetric decays to reduce systematic effects, the results $M(\eta) = 547.843 \pm 0.051$ MeV/c$^{2}$ and $M(K^{0}) = 497.625 \pm 0.031$ MeV/c$^{2}$ were ob...
