Abstract

The momentum spectrum of the π+ in stopping K+ decays was measured by use of a high-resolution magnetic spectrometer to search for a discrete peak due to a neutral boson X0 in a two-body decay K+→π+X0. An upper bound of the branching ratio R (K+→π+X0) is presented for the mass range of X0 from 10 to 300 MeV/c2.
