New measurements of the η and K0 masses have been performed using decays to 3π0 with the NA48 detector at the CERN SPS. Using symmetric decays to reduce systematic effects, the results M(η) = 547.843 ± 0.051 MeV/c2 and M(K0) = 497.625 ± 0.031 MeV/c2 were obtained.

Abstract
New measurements of the η and K0 masses have been performed using decays to 3π0 with the NA48 detector at the CERN SPS. Using symmetric decays to reduce systematic effects, the results M(η) = 547.843 ± 0.051 MeV/c2 and M(K0) = 497.625 ± 0.031 MeV/c2 were obtained.File in questo prodotto:
