New measurements of the eta and K(0) masses have been performed using decays to 3pi(0) with the NA48 detector at the CERN SPS.

Abstract

New measurements of the eta and K(0) masses have been performed using decays to 3pi(0) with the NA48 detector at the CERN SPS. Using symmetric decays to reduce systematic effects, the results M(eta) = 547.843 +/- 0.051 MeV/c(2) and M(K-0) = 497.625 +/- 0.031 MeV/c(2) were obtained. (C) 2002 Elsevier Science B.V.
